gpio: samsung: refactor gpiolib init for exynos4/5
Only code move, no functional change. Main reason to do this was to get rid of the warnings: drivers/gpio/gpio-samsung.c: In function 'samsung_gpiolib_init': drivers/gpio/gpio-samsung.c:2974:1: warning: label 'err_ioremap4' defined but not used [-Wunused-label] drivers/gpio/gpio-samsung.c:2722:47: warning: unused variable 'gpio_base4' [-Wunused-variable] without adding more ifdef mess. I think this whole file would do well being coverted over to a platform driver and moving most of the tables out to SoC code and/or device trees, but since that changes init ordering it needs to be done with some care, i.e. not at this time.
