TPSCHROME NTC readings didn't match battery gas gauge temperature. The charging was turned off by TPSCHROME too early, and was resumed too late. This change disables TPSCHROME thermal protection in T40 by set charging voltage and current to 100%.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

Build Options
=============
- CONFIG_WATCHDOG_HELP
Try to detect a watchdog that is about to fire, and print a trace.
This is needed on STM32, where the independent watchdog has no early
warning feature and the windowed watchdog has a very short period.
- CONFIG_PANIC_NEW_STACK
When reporting a panic, change to a completely new stack. This might
help get a useful trace out a situation where the stack or stack
pointer has been corrupted.
- CONFIG_PANIC_HELP
Report extra information about a panic, such as the fault address,
here shown as bfar. This shows the reason for the fault and may help
to determine the cause.

- CONFIG_ASSERT_HELP
Report assertion failures in a vebose manner to aid debugging. When
enabled an ASSERT() which fails will produce message in the form:
ASSERTION FAILURE '<expr>' in function() at file:line
- CONFIG_CONFIGURE_BOARD_LATE
Define this to call configure_board_late() after initial system init
is complete (and after GPIOs are set up).
- CONFIG_AC_POWER_STATUS
Monitor the state of the AC power input and drive out a GPIO to
the AP indicating this state. The GPIO will be driven low when
AC power is not connected, and high when it is connected. This
uses GPIO_AC_STATUS for this purpose.
