Vineet Gupta ce7ec3d752 ARC: mm: arc700: Don't assume 2 colours for aliasing VIPT dcache
commit 08fe007968 upstream.

An ARC700 customer reported linux boot crashes when upgrading to bigger
L1 dcache (64K from 32K). Turns out they had an aliasing VIPT config and
current code only assumed 2 colours, while theirs had 4. So default to 4
colours and complain if there are fewer. Ideally this needs to be a
Kconfig option, but heck that's too much of hassle for a single user.
