Log Message:
EXYNOS rewrite step 3 of N: Add aliases for gpio pins

This adds the GPIO aliases that will be used for board-independent driver
lookup until we have FDT.

The idea here is that each pin used by any driver is given a name that
the driver knows that is independent of the gpio bank name.  The mapping
from the alias to the actual gpio bank + pin number is done in this file
and a lookup function is added to exynos_gpio.c that allows a driver to
ask for a gpio pin by the alias name, blisssfully unaware that there is
an underlying GPIO bank name.

Once set up with all the drivers, it should then be possible to move to a
different vendor's board simply by modifying exynos_machdep.c
