[PATCH] chardev: GPIO for SCx200 & PC-8736x: refactor scx200_probe to better segregat...

Pull shadow-reg initialization into separate function now, rather than doing
it 2x later (scx200, pc8736x).  When we revisit 2nd drvr below, it will be to
reimplement an init function, rather than another refactor.
