[PATCH] chardev: GPIO for SCx200 & PC-8736x: fix gpio_current, use shadow regs

Add a working gpio_current() to pc8736x_gpio.c (the previous implementation
just threw a dev_warn), and fix gpio_change() to use gpio_current() rather
than the incorrect (and temporary) gpio_get().  Initialize shadow-regs so this
all works.
