ec/google/chromeec: Add support to report fan speed via ACPI
Add fan speed rpm control for DPTF based Active2 policy as per
document #626708, by utilizing existing FAN0 variable from
src/ec/google/chromeec/acpi/emem.asl#18.
There is no corresponding EC change required for this policy
support because EC fan code already exporting this rpm value
using EC_MEMMAP_FAN for FAN0.
BUG=b:224457192
BRANCH=None
TEST=Built and booted on ADL-P based Brya system and
verify the fan speed in rpm under sysfs path
cat /sys/bus/acpi/devices/INTC1048\:00/fan_speed_rpm.
