ARM: IGEP0033: rename config file to am335x_igep0033.h

There seems to be a naming convention for the configuration
files for boards using the same SoC family. This makes
easier to do changes that affect different boards based
on the same SoC.

Since the IGEP COM AQUILA use a TI AM335x processor is better
to rename its board config to use this naming scheme.
