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