mainboard/puff: Fix ACPI tables to advertise correct features

Provide Puff with it's own copy of ec.h copied from the
baseboard/includes however with the battery, lid and ps2
defines stripped.

This is to ensure the correct ASL is generated so that we don't
advertise PS2 keyboard support and battery/lid interrupts which
don't exist.

V.2: drop EC_ENABLE_ALS_DEVICE as well.
V.3: set MAINBOARD_EC_SMI_EVENTS to 0 and drop
     EC_HOST_EVENT_LID_CLOSED smi event.
V.4: drop EC_HOST_EVENT_MODE_CHANGE &&
     provide wake pin for EC for _PRW WoL method
V.5: drop EC_HOST_EVENT_KEY_PRESSED
