ARM: cache_v7: Various minor cleanups

Remove two gratuituous blank lines, uses u32 (instead of int) as the
type for values that will be written to a register, moves the beginning
of the variable declaration section to a separate line (rather than the
one with the opening brace) and keeps the function signature on a single
line where possible.
