powerpc/32: Curb objtool unannotated intra-function call warning
...
objtool throws the following warning:
arch/powerpc/kexec/relocate_32.o: warning: objtool: .text+0x2bc: unannotated intra-function call
Fix this warning by annotating intra-function call, using
ANNOTATE_INTRA_FUNCTION_CALL macro, to indicate that the branch target
is valid.

powerpc: Remove CONFIG_FSL_BOOKE
...
PPC_85xx is PPC32 only.
PPC_85xx always selects E500 and is the only PPC32 that
selects E500.
FSL_BOOKE is selected when E500 and PPC32 are selected.
So FSL_BOOKE is redundant with PPC_85xx.
Remove FSL_BOOKE.
And rename four files accordingly.
cpu_setup_fsl_booke.S is not renamed because it is linked to
PPC_FSL_BOOK3E and not to FSL_BOOKE as suggested by its name.

powerpc: Avoid link stack corruption in misc asm functions
...
bl;mflr is used at several places to get code position.
Use bcl 20,31,+4 instead of bl in order to preserve link stack.
