  [ARM][NFC] Tidy up subtarget frame pointer routines

getFramePointerReg only depends on information in ARMSubtarget,
so move it in there so it can be accessed from more places.

Make use of ARMSubtarget::getFramePointerReg to remove duplicated code.

The main use of useR7AsFramePointer is getFramePointerReg, so inline it.
