Fix bogus ioctl definitions

Fix bogus ioctl definitions

[Andreas Schwab]

This patch fixes the definitions of a few ioctl numbers: the third
argument of _IOR/_IOW/_IOWR is supposed to be a type, not a number.
Fortunately the actual values will not change (on a 32 bit system),
except that PMU_IOC_GRAB_BACKLIGHT should have been _IO('B', 6) in the
first place.

Andreas.
