Previously usb_charger.c supported only pi3usb9281, but now support for
additional parts is required. Move pericom-specific code (including the
usb_charger tasks that handles various quirks of that part) to the
pi3usb9281 usb_switch driver.
Going forward, usb_switch drivers must implement
usb_charger_set_switches() and must have some method (such as a task or
interrupt handler) to update charge_manager with information about
attached chargers.

GPIO console commands currently only show input voltage level,
and can only set level on predefined outputs.
This change allows GPIOs to be cycled between output, input,
and alternate function, as well as displaying the mode and
asserted level (if any) in gpioget.
This change creates CONFIG_CMD_GPIO_EXTENDED
as the internal gpio interface needs to be changed to support
this, and I can't test the other architectures. It may be
worthwhile to add this for all, or not.
This change is also necessary also for servo micro JTAG and PD
UART support, as several pins are tied together on the flex
and stm32 outputs need to be variously active or in high-z
depending on mode.

Now that the cr50 no longer uses this array to store its pinmux config
we can move it out of the header file, removing it from the public
interface for GPIO code. This allows us to start modifying this struct
more easily.

EC boot / hash computing can be a bottleneck for system boot time.
Reduce this bottleneck by running our processor at 48 MHz through boot,
until vboot hashing of RW completes.
BUG=chrome-os-partner:49583
TEST=Boot chell, verify vboot hash completes within 1 sec of EC boot and
'cbmem' delta between 'vboot select&load kernel' and 'finished EC
verification' is reduced to ~250 ms (which includes sysjump time).

In case of no battery condition, current code sets the charger input
current to the charger maximum input current. To avoid damage to the
board, set the charger input current to the maximum current that the
board can support.
BUG=none

TEST=Manually tested on kunimitsu, removed the battery & then using EC
console command 'charger', verified that the current value is set
to 3000mA.

This change use a simple counter to to prevent ec enter sleep if there's

counter to prevent preemptive conditions.

This patch introduces HOST_CPPFLAGS to be used for all
objects being compiled with HOSTCC rather then the target
compiler.
Since glibc is not linked into the EC, no glibc include files
should be included in the EC code base. Hence, create local
definitions for clock_t and wchar_t that match what the glibc
include would have done, and remove some unneeded includes.
Due to very eager optimization, we have to give gcc a little
notch to not kick out memset.
