The macros assume that constants that are compared against
"addr" are either unsigned or less than INT_MAX.
In some cases it is not true so change costants to unsigned
using U32_C macros.
The correct solution would be to change teh MEM_ADDR, PMM_BASE, etc.
to be unsigned long but currently "U" suffix is appended in various
places so the assumption is that those macros use default definition
(which is int).

Put "addr" into brackets by the way since it could be an expression
rather than one variable.
