parisc: Remove flush_user_dcache_range and flush_user_icache_range

Browse Source 
The functions flush_user_dcache_range() and flush_user_icache_range()
are only used by the parisc signal handling code.  This code only needs
to flush a couple of lines, so the threshold check is unnecessary
overhead.
