  [AArch64] Fix gcc warning about mix of enumeral and non-enumeral types [NFC]

Change the return type of
 findScratchNonCalleeSaveRegister
to Register instead of unsigned.

Every place the function is called we already put the returned value in a
Register variable or compare it with another Register.

This fixes some gcc warnings:
