Yeah, I think it should probably land before MFD_PM8XXX's BROKEN
removal, just to eliminate randconfig breakage noise.  I double-checked,
and it looks like at least the other drivers that depend on MFD_PM8XXX
still build (with a couple sparse warnings).

Also.....it's driving me nuts that some of the pm8xxx drivers use
"pm8xxx-foo", and others use "pmic8xxx-foo"...
