Add a new pin PMIC_THERM_L (PA1) since AP_RESET_L (PA15) is removed.
To force shutdown, drive PMIC_THERM_L to low (default high) for 32us.
Also rename set_pmic_pwrok() -> set_pmic_pwron(). And add a debounce time
for PMIC_PWRON_L pin.

'power off' shutdowns the AP immediately.
'reboot' reboots the EC and resets the AP as well.
'sysjump RW' still keeps AP alive.

These boards are unloved and unsupported. They'll never grow up to be
laptops, and hardware is increasingly hard to come by.
Comparable functionality is available in the other, more-loved boards.
Removing these boards speeds up util/make_all.sh by 40%. (If you're
not running that before every upload, you should be...)

This fixes a bug in which after a sysjump, the sleep_mask is

must notable of which is that a flashrom write fails with an
EC protocol mismatch error.

The common/ subdir was getting cluttered. Move drivers for external
components to a new driver/ tree, and move what used to be called
chipset_*.c to a new power/ directory.
This does not move/rename header files or CONFIG options. That will
be done in subsequent steps, since moving and modifying .c files in
the same CL is harder to review.
