Subject: Fix gpio-mdio driver to work for gpio's that return something
	other than 0 and 1.

The gpio-mdio driver seems to assume GPIOs return 0 and 1, although that
doesn't seem to be the case.  I see return values of 0 and 0x1000000
for the GPIO I happen to be using.  A simple application of !! solves
that though.

Tested on a RuggedCom RX5000 (mpc8360e based).
