ARM: s5p: cut the custom ARCH_NR_GPIOS definition

Browse source 
The number of GPIOs defined for the different S5P platforms using
the tricky #define macros are actually as follows:

S5P64x0: 180 GPIOs
S5PC100: 115 GPIOs
S5PV210: 252 GPIOs

The include file <asm-generic/gpio.h> will automatically bump us
to 256 GPIOs which is a nice default value that happens to encompass
all the S5P platform requirements under its roof.

Cut ARCH_NR_GPIOS and the custom spacing macro for extra GPIOs
that is not used anywhere in the kernel.

Use additional GPIO space in addition to the GPIO's the SOC
provides. This allows expanding the GPIO space for use with
GPIO expanders.
