arm64: Reorganize payload entry code and related Kconfigs

Browse Source 
This patch slightly reorganizes arm64/boot.c with the aim of being more
readable: the secure monitor entry is now guarded by an explicit if
statement for its Kconfig rather than hiding than in the corresponding
header file. This makes it clear that there are two (soon three)
separate code paths here.
