ARM: 7062/1: cache: detect PIPT I-cache using CTR

The Cache Type Register L1Ip field identifies I-caches with a PIPT
policy using the encoding 11b.

This patch extends the cache policy parsing to identify PIPT I-caches
correctly and prevent them from being treated as VIPT aliasing in cases
where they are sufficiently large.

scripts/sortextable: silence script output

The exception table sorter outputs one line every time
it gets called, e.g. 'sort done marker at 66dc00', which
is slightly annoying when doing 'make -s' which is otherwise
completely silent. Since that output is not helpful to
most people building the kernel, turn it off by default.
