MIPS: r4kcache: Use correct base register for MIPS R6 cache flushes
Commit 934c79231c1b("MIPS: asm: r4kcache: Add MIPS R6 cache unroll functions") added support for MIPS R6 cache flushes but it used the wrong base address register to perform the flushes so the same lines were flushed over and over. Moreover, replace the "addiu" instructions with LONG_ADDIU so the correct base address is calculated for 64-bit cores.
