Helge Deller 2c98a8fbd6 parisc: Flush correct cache in cacheflush() syscall 
The assembly flush instructions were swapped for I- and D-cache flags:

SYSCALL_DEFINE3(cacheflush, ...)
{
	if (cache & DCACHE) {
			"fic ...\n"
	}
	if (cache & ICACHE && error == 0) {
			"fdc ...\n"
	}

Fix it by using fdc for DCACHE, and fic for ICACHE flushing.
