pinctrl: sh-pfc: Add generic bias register description

Browse Source 
Add a generic way to describe bias registers (for pull-up/down control),
like is already done for config and drive registers.

This makes the sh-pfc core code aware of these registers, which will
ease introducing suspend/resume support later.
