ARM: 8292/1: mm: fix size rounding-down of arm_add_memory() function
The current rounding of "size" is wrong:
- If "start" is sufficiently near the next page boundary, "size"
is decremented by more than enough and the last page is lost.
- If "size" is sufficiently small, it is wrapped around and gets
a bogus value.
