Randall Spangler e764bdbb03 link:re-enable fan RPM controller when needed
Previously, any command which set the fan duty manually would leave
the PWM RPM controller disabled.  Setting the fan back to auto mode
via 'ectool autofanctrl' or 'autofan' or 'ectool pwmsetfanrpm'
wouldn't turn the controller back on.  Now it does.

BUG=chrome-os-partner:14307
BRANCH=link
TEST=manual

  - Reboot in recovery mode and wait for INSERT screen

  - From EC console
    fanduty 100 -> fan turns on all the way
    faninfo -> mode is duty
    fanset 6000 -> fan turns down to a lower level
    faninfo -> mode is rpm
    fanduty 0 -> fan turns off all the way
    faninfo -> mode is duty
    (wait a min or so for the system to heat up)
    autofan -> fan turns on
    faninfo -> mode is rpm

  - Reboot normally

  - From root shell
    ectool fanduty 100 -> fan turns on all the way
    ectool pwmsetfanrpm 6000 -> fan turns down to a lower level

- 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_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.

	=== EXCEPTION: 03 ====== xPSR: 01000000 ===========
	r0 :0000000b r1 :00000047 r2 :60000000 r3 :200013dd

	mmfs = 00008200, shcsr = 00000000, hfsr = 40000000, dfsr = 00000008

- 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.

- CONFIG_PMU_FORCE_FET

	Force switching on and off the FETs on the PMU controlling various
	power rails during AP startup and shutdown sequences.
	This is mainly useful for bringup when we don't have the corresponding
	sequences in the AP code.
