drvs/lenovo/hybrid_graphics/romstage: Fix dGPU activation
While the older boards use a GPIO that has no state, the newer boards'
PMH7 does have a state, that even remains after reboot.
Don't assume default values in PMH7 and instead always program it.
Fixes dGPU doesn't show up when switching from integrated to discrete
GPU. The workaround of removing all power is no longer necessary.
