mb/google/poppy/variants/nautilus: Set CABC_EN to GPO high before EDP power on
If GPP_E22(CABC_EN) remained floating GPI(SoC default) at V3.3_DX_EDP on,
it may cause damage on the GPIO pad.
To prevent, we would set this pad to GPO on romstage before EDP power on.
Since we need to cover all systems in market, I put it into romstage
instead of early_gpio_table.
BUG=b:111860510
BRANCH=poppy
TEST=Verified CABC_EN is set to GPO high 5ms before EDP power on
