nios2: Pseudo implement dcache_status/enable/disable()

AFAIK the NIOS2 architecture does not have any possibility to
dynamically switch off the data cache. So _status() always reports 1 and
_enable/_disable() just issue a flush of everything.

For example, common/cmd_elf.c depends on these symbols.
