mb/google/brya/variants/hades: Update GPU power sequencing to add Hades support
Add GPU power sequencing changes for the Hades baseboard and variant.
Some signals were added, moved or inverted.
Based on implementation from Agah.
Moved signals:
GPIO_1V8_PWR_EN GPP_E11
GPIO_NV33_PWR_EN GPP_E2
GPIO_NV33_PG GPP_E1
New signals:
GPIO_NV12_PWR_EN GPP_D0
GPIO_NV12_PG GPP_D1
Inverted signals:
GPIO_FBVDD_PWR_EN GPP_A19
ifdef's will be dropped once the Agah variant is retired.
BUG=b:269371363
TEST=builds and verified on Agah that DGPU is still detectable (lspci)
