gpio interrupts for Samsung SoCs.

Add locking to each GPIO bank to allow for SMP capable code
to use the gpiolib functions. See the gpio-core.h header file
for more information.

Rename mach-s3c2410/include/mach/gpio-core.h to mach/gpio-track.h so that
it can be included by <plat/gpio-core.h> when needed.
Eliminate all other empty gpio-core.h files and just include the
<plat/gpio-core.h> as necessary.

Move the gpio.c code containing the core gpiolib and GPIO support to
plat-samsung from plat-s3c as it is used by all current Samsung SoCs.
Note, we didn't move this to gpiolib.c as it contains code that is not
strictly for gpiolib support and the 4bit code is already called gpiolib.c
so make the change easier by not renaming both files in one go.
