Paul Mundt e055d41ff5 sh: Build fix for disabled caches.
This fixes up the build when caches are disabled, by linking in all of
the cache routines directly. This paves the way for splitting out
separate I and D cache disabling, similar to what sh64 had, and which
we want for SH-X3 anyways.

# Special flags for fault_64.o. This puts restrictions on the number of
# caller-save registers that the compiler can target when building this file.
# This is required because the code is called from a context in entry.S where
# very few registers have been saved in the exception handler (for speed
# reasons).
# The caller save registers that have been saved and which can be used are
# r2,r3,r4,r5 : argument passing
# r15, r18 : SP and LINK
# tr0-4 : allow all caller-save TR's. The compiler seems to be able to make
# use of them, so it's probably beneficial to performance to save them
# and have them available for it.
#
# The resources not listed below are callee save, i.e. the compiler is free to
# use any of them and will spill them to the stack itself.
