mb/google/brya/var/kinox: Support DPTF oem_variables
Enable DPTF oem_variables and override based on charger type.
BUG=b:230803675
TEST=1. With 90W adapter, check ACPI object ODVX and oem_variable[0]=1
Name (ODVX, Package (0x06)

0x00000000
})
2. With 65W adapter, check ACPI object ODVX and oem_variable[0]=0
Name (ODVX, Package (0x06)
{
0x00000000,
0x00000000,
