Add support for low level debugging on AM335X EVM (AM33XX family).
Currently only support for UART1 console, which is used on AM335X EVM
is added.

This patch fixes a bug, (wrongfully) resetting the value of
LPC32XX_CLKPWR_MS_CTRL back to its initial contents (after careful setup). This
was discovered only with a board/bootloader combination (EA3250) where the
contents of the respective register wasn't already at the correct value on
Linux boot.

ARCH_NR_GPIOS was defined statically to include exactly all SoC specific GPIOs.
Now if additional GPIOs need to be added dynamically, e.g. via DT, none are
available. Removing the mach specific setting, leaving ARCH_NR_GPIOS to the
default of 256 (currently in include/asm-generic/gpio.h).

mach-s3c24xx/include/mach/gta02.h header file contains defines
which are now not used anywhere, remove them.

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);

There is now no more users of these compatibility definitions,
so remove them.

Replace the S3C24XX SoC specific calls with the common gpiolib
API. This removes one more user of an obsolete GPIO API.

Replace SoC specific GPIO functions with the gpiolib API. The LED
gpio is freed right after it is configured so it can be acquired
in the s3c24xx_led driver.
This change is required for converting the s3c24xx_led driver
to the gpiolib API.

The backlight gpio must not be left requested in the board
code, otherwise s3c24xx_led driver can't successfully claim it.
So request the backlight gpio, configure it to proper state and
gpio_free right away.
This change is required for converting the s3c24xx_led driver
to the gpiolib API.
