[PATCH] power_state and __iomem for mediabay.c

[Paul Mackerras <paulus@samba.org>]

This patch does the power_state -> power.power_state conversion for
drivers/macintosh/mediabay.c and makes it use void __iomem * for
ioremap cookies.  Once the IDE code is converted to not use unsigned
long for MMIO register addresses, I will be able to remove a few casts
from here.
