In order to test certain devices in the test lab using cased closed
debugging (CCD), we need a mechanism to programmatically "press" the
recovery button. Even though this signal is being buffered through the
EC to the AP, and the EC could theoretically set it if needed, we cannot
trust the EC in its RO image since it may speak to the outside world
over USB PD.
Instead, this commit introduces a console command on cr50 that can be
used to force the recovery button state to be pressed. However, it is
gated behind the CCD capabilities defaulting to the IfOpened state.
Additionally, a new vendor command is added to query the trusted state
of the recovery button. The AP should use this command instead of
trusting the GPIO connected to it.

A common failure condition on the i2c bus is when the master
unexpectedly stops clocking the bus while the slave is driving the SDA
line low. In this case the master is not able to issue Stop or Start
sequences, which makes the bus unusable.
Good slave controllers are able to detect this condition and recover
from it by removing the pull down from the SDA line. This patch adds
this capability to the g chip i2c slave controller.
A new timer function is created which samples the SDA line twice a
second. If it detects that SDA is low in two consecutive invocations
and the number of i2cs read interrupts has not advanced, it decides
that the "hosed slave" condition is happening and reinitializes the
i2c driver, which removes the hold from the SDA line.
Even though the state of the SDA line is supposed to be accessible
through the I2CS_READVAL register, it in fact is not, reads always
return zero in the SDA bit. To work around this a GPIO (port 0, bit
14) is being allocated to allow to monitor the state of the line, it
is multiplexed to the same pin the SDA line uses.
When the AP is in low power modes the SDA line is held low, this state
should not trigger i2c reinitializations.

Some USB interface handlers need to know when USB has been
successfully resumed after a wake event. For example, this is
useful so that HID keyboard can send the events at the right time.
BRANCH=none
BUG=b:35775048
TEST=Using USB HID keyboard patches to queue keys in a FIFO:
After USB autosuspends, press a single key and hold it. Without
this patch the endpoint data only gets reloaded on the _next_
event.
TEST=On hammer, I2C passthrough still works.

When servo_v4 acts as a debug test system (DTS) its expected use
case is for triggering CCD mode and Faft testing. To that end, its
desired default data role is to be a UFP so that the enet and USB
port are accessible by the DUT. However, when servo is acting a
regular SRC port, it makes more sense for the data role pairing to
be consistent with a normal SRC port device which is SRC/DFP.
BUG=b:64720447
BRANCH=servo
TEST=Tested with Eve using twinkie USB PD analyzer. Verified that when
DTS mode is enabled a data role swap request is sent to the DUT and
when DTS mode is disabled that servo_v4 does not send a data role swap
request.

To enable console with DMA, we need to specifically
remap DMA channels for USART1.
ch2/3 and ch6/7 are already used by SPI1/2 modules.
So we have to remap USART1_TX to ch4 and USART1_RX to ch5.

When CONFIG_USB_PD_MAX_SINGLE_SOURCE_CURRENT is defined for a board, as
its name implies, the board can source a higher current if there is
only one port acting as a source.
This commit fixes an issue with selecting the right source capability
message to advertise. charge_manager_get_source_pdo() was simply
checking if there was more than one sink connected, instead of checking
if there were any *other* sinks connected. In the event that a sink
was connected to a different port, we would advertise the max source
PDO.
BUG=b:64037926, b:35577509
BRANCH=gru,eve,reef
TEST=Connect sink to port 1. Connect a AMA to port 0 that claims that
VBUS isn't necessary. Start sending source caps, verify that the max
PDO is not being advertised in the source caps.
