From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

The RPX board is not supported by the kernel because CONFIG_RPXCLASSIC and
CONFIG_RPXLITE symbols and not defined anywhere. Clean-up the m8xx_pcmcia
driver a little bit.

NOTE: this commit is independent, and I can merge it via the MTD tree with the
rest of the patches of this series. Of course, an ACK would be great to have.
And of course, if PCMCIA people wish to merge it via their tree, it is also
nice, just let me know.
