Currently, when we jump from RO to RW, we forget our USB PD state.
To recover from this, we send a SOFT_RESET (resetting the counters...),
then either the USB PD partner is happy about it and we can continue,
or it will issue a HARD_RESET to recover from our mismatched vision of
the current connection (e.g wrong role) resulting in a reset of VBUS.
The following use-case is still problematic:
if the system is not write-protected (ie it does USB PD negotiation in
RO EC) and we have no battery (or fully drained-one) as buffer, when we
are connected to a PD power supply, if it issues the HARD_RESET
mentioned above, we are going to brown-out.
It's happening with power-supplies supporting DR_SWAP, the RO EC will
negotiate a power-contract (as a sink), then try to reverse data role
(from UFP to DFP) to identify the power-supply. We end-up being
Sink/DFP, then when we sysjump to RW, we reset roles and send the
SOFT_RESET as Sink/DFP, the power-supply identifies the incorrect data
role and issues the HARD_RESET browning us out.
As a workaround, now we never ask for the DR_SWAP in RO firmware and
stays Sink/UFP.
This is not affecting regular write-protected machines (which are not
doing USB PD in RO EC). For developers, we are no longer doing the
DR_SWAP in RO mode, this is mostly innocuous for a regular power-supply,
but this would break the docking use-case. Normally, we will do it as
soon as we have jumped to RW, so the dock should still work unless the
developer is using the machine with RO EC (eg EC development with
soft-sync disabled).

The function bc12_detect was using a msleep(312) to allow for enough
time for the bd9995 to determine the charger type. Putting the USB_CHG
task to sleep for this period of time means that the USB_CHG task is
not able to process interrupts from the bd9995 during that time. This
is a particular problem when Try.SRC is enabled and a charger is
connected. VBUS will only remain present for ~40-50 msec, and
when it goes away, the discharge circuit should be engaged. However,
the USB_CHG task is still in the 312 mSec sleep from when VBUS was
detected. The result is that discharge circuit is not engaged. It was
observed that processing of charger interrupts could be delayed
upwards of 500 msec.
On Eve with the EVT charger, VBUS was not discharging without the
discharge circuit being enabled. This resulted in excessive connect
time as the Try.SRC cycle repeated many times until a case where the
discharge circuit was not disabled when VBUS detect occurred and this
finally allowed the charger to attach.
This CL modifies the USB_CHG task main loop so that a wait timer is
used when bc12_type needs to be read from the charger. There is a wait
timer mark per port. If the mark value is 0, then a wait timer is not
required and the task is put to sleep with -1. Each time the task is
woken, either from the interrupt or wait event timer, the current time
is checked against the timer mark for each port. The function that
reads the bc12_type will return a 1 if the type is still not available
and will return 0 if either VBUS is no longer present, or the
bc12_type was successfully determined.
With this change in place the discharge circuit is reliably
enabled/disabled within ~5-10 mSec of VBUS changes.

Also tested with various different chargers on both Eve and Reef
platforms. In addition, temporarily changed the initial deferred time
to 100 mSec and validated the path where vbus_provided is not true and
that additional deferred calls were initiated until bc12_type is valid.

Starting with
be294d4ef "hammer: Only define required options for RO and RW"
we do not define CONFIG_RWSIG for the RW section. However,
we want CMD_UNLOCK_RW to be usable when EC is in RW section, to
unlock itself in prevision for an update on the next reboot.

The virtual battery "energy" readings were totally broken. Rather
than reporting things in units of "10 mW" they were reporting things
in units of "10 uW". That's because they were doing this math:
result = mV * mA / 10
Said another way:
result = (V / 1000) * (A / 1000) / 10
result = (V * A) / (100000) / 10
result = W / 1000000 / 10
result = uW / 10
Aside from the fact that clients were expecting things in "10 mW"
instead of "10 uW", we got even more random results. That's because
we return to the client in a 16-bit variable, so we were kinda
randomly truncating things.
Doh.

Unfortunately when you try to report sane values for "10 uA" in a
16-bit result, it doesn't work too well (

If charging current is set to 0mA during charging, reference of
charge current feedback amp (VREF_CHG) is set to 0V. Hence the DCDC
stops switching (because of the EA offset). To eliminate this issue,
disable/enable charger depending on the charging current is zero
or non-zero respectively.
