[PATCH 2/9] aarch64: Align SFrame terminology in comments to specs and x86

[Jens Remus <jremus@linux.ibm.com>]

Use the term "frame pointer" (FP) instead of "base pointer". This aligns
with the terminology used in the SFrame specification. Additionally it
helps not to confuse "base-pointer register" with the term "BASE_REG"
used in the specification to denote either the SP or FP register.

While at it align the frame-pointer and return address register comments
to the x86 AMD64 ones.

	  specs and x86 AMD64.

Notes (jremus):
    This patch can be dropped, if subsequent patch "sframe: Enhance comments
    for SFRAME_CFA_*_REG macros" gets accepted.
