Subrata Banik e8097f7a28 mb/google/rex: Add ELAN6918 touchscreen 
ELAN6918 Power Sequencing seems not perfectly matching
with the previous platforms and setting GPP_C06 to high prior
to the power sequencing is actually makes it work.

Ideally Power Sequencing should be as below for ELAN6918 (in ACPI)
`POWER enabled -> RESET deasserted -> Report EN enabled`

But below sequence is only working currently:
`Report EN enabled (ramstage) -> POWER enabled (ACPI) -> RESET
 deasserted (ACPI)`

BUG=b:247029304
TEST=Verified ELAN touch panel is working as expected after booting
Google/rex device to ChromeOS.
