Set the GPIO pin mode to external interrupt when configuring
an IRQ_EINT's IRQ type.

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.

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.
