Remove or amend casts to comply with Rule 11.8.

Fix violations by adding missing const qualifier in cast.
Fix violations by removing unnecessary cast.
Change type of operands from char* to uintptr_t: uintptr_t is
the appropriate type for memory address operations.

No functional changes.

I consider it good practice to at least briefly say what the rule is

What about PPC's identical code?

If the ARM part is accepted, I will include this change in an upcoming series for Rule 11.8 (which I'm working on), otherwise in v4.
