arm920t: fix write memory operations with caches enabled

Commit ff5ec942d80a34e20b5a3ca3328f7e6a55fb309b made this target
always use generic arm7_9 memory write routines for software
breakpoints which resulted in inability to debug and single-step
sources in Gdb when icache is active as generic routine doesn't
invalidate it. This should fix it (and is real-life tested against
Samsung S3C2442). I expect other arm7-9 targets to be affected as
well.
