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) Change-Id: I0b8efe7a34102cf61d4f784103c4a4f9337213f7 Signed-off-by: Tarun Tuli <taruntuli@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/73896 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Ivy Jian <ivy.jian@quanta.corp-partner.google.com>
