ARM: S3C24XX: Remove unused GPIO definitions for port J 

There is no need now for individual GPIO port J pin control bit
definitions, the GPIO0..12 pins can be configured using the gpiolib
API. The GPJ* register address offset definitions for S3C2413 are
moved to the common mach-s3c24xx/include/mach/regs-gpio.h header.
These are still used outside of the gpio-samsung driver by PM code.

Switching GPJ port to camera function can be done for example with:
s3c_gpio_cfgall_range(S3C2410_GPJ(0), 13, S3C_GPIO_SFN(2), S3C_GPIO_PULL_NONE);
