bd117bd161 [ARM] S3C64XX: Initial support for PM (suspend to RAM)

suspend-to-RAM to sleep.

Includes basic debugging for use with the SMDK6410 usign the
LEDs on the baseboard.

333053733f [ARM] S3C64XX: Add EINT group regs and move IRQ_EINT to regs-gpio.h
Add definitions for the EINT group registers and move the EINT IRQ
register definitions out of arch/arm/plat-s3c64xx/irq-eint.c so that
they are available for re-use with PM and the other code.

c8532db7f2 [ARM] 5411/1: S3C64XX: Fix EINT unmask
Currently the unmask function for EINT interrupts was setting the mask
bit rather than clearing it.  This was also previously reported and
fixed by Kyungmin Park <kyungmin.park@samsung.com> and others.

80789e7915 [ARM] S3C64XX: Add IRQ_EINT support
Add the necessary code to support IRQ_EINT(x) on
the S3C64XX series of CPUs.

Note, since there is no GPIO configuration support
in the kernel, the irq set_type method does not
configure the relevant pin to interrupt.
