[PATCH v5 02/31] target/arm: Rename TBFLAG_A32, SCTLR_B

[Richard Henderson]

We're about to rearrange the macro expansion surrounding tbflags,
and this field name will be expanded using the bit definition of
the same name, resulting in a token pasting error.

So SCTLR_B -> SCTLR__B in the 3 uses, and document it.
