powerpc: Restore some misc devices to our configs
Uwe Kleine-König reported:
while working on an defconfig (arm/mx27) I noticed that just updating
it[1] results in removing CONFIG_EEPROM_AT24=y. The reason is that
since commit
v2.6.36-5965-g5f2365d (misc devices: do not enable by default)
MISC_DEVICES isn't enabled anymore by default. So all defconfigs that
have CONFIG_SOME_SYMBOL=y (or =m) (with SOME_SYMBOL depending on
MISC_DEVICES) but not CONFIG_MISC_DEVICES=y suffer from the same
problem.
This restores those misc devices to the powerpc defconfigs.
