ARM: S3C64XX: Fix keypad setup to configure correct number of rows

The call to s3c_gpio_cfgrange_nopull() takes a size and base
but this looks like it is trying to do base and end. This means
it is configuring too many GPIOs and on the case of the Cragganmore
means we're seeing an overflow of the ROW pins causing problems
with the keyboard driver.
