ARM: 7772/1: Fix missing flush_kernel_dcache_page() for noMMU

Browse Source 
commit 63384fd0b1509acf522a8a8fcede09087eedb7df upstream.

Commit 1bc3974 (ARM: 7755/1: handle user space mapped pages in
flush_kernel_dcache_page) moved the implementation of
flush_kernel_dcache_page() into mm/flush.c but did not implement it
on noMMU ARM.
