target: convert 'unsigned' to 'unsigned int'

Conversion done with
	checkpatch --fix-inplace -types UNSPECIFIED_INT

Ignore the cast as they could be better addressed.
Fix only minor additional checkpatch issue (spacing and line
length).

Use Checkpatch-ignore below for the function pointers in the file
'armv7a_cache_l2x.h' that do not assign the identifier names to
the function arguments.
Most of these struct are unused and should be fixed or dropped.

Checkpatch-ignore: FUNCTION_ARGUMENTS
