[PATCH v1 3/8] powerpc/fsl_booke: Take exec flag into account when setting TLBCAMs

[Christophe Leroy]

Don't force MAS3_SX and MAS3_UX at all time. Take into account the
exec flag.

While at it, fix a couple of closeby style problems (indent with space
and unnecessary parenthesis), it keeps more readability.
