mb/lenovo: dGPU power handling on T430, T530
Enable dGPU power handling on Lenovo ThinkPad T430, T530 via PMH7 register 0x50.
Although there's no Thinker-1 chip on these models according to schematics, dGPU power control via PMH7 works the same as on T420/T520, so they can be considered Thinker-1-compatible.
It can be tested from linux userspace using util/pmh7tool.
To turn dGPU power off: pmh7tool -c 0x50 7 pmh7tool -c 0x50 3
To turn it on: pmh7tool -s 0x50 3 pmh7tool -s 0x50 7
To check whether it is on (bash): reg=0x$(pmh7tool -r 0x50) echo "$(( (( reg & 0x08 )) >> 3 ))" or just `pmh7tool -b 0x50 3` with https://review.coreboot.org/#/c/coreboot/+/28388/
Tested on ThinkPad W530.
