ARC: [mm] Prevent stray dcache lines after__sync_icache_dcach()
Flush and INVALIDATE the dcache page. This helper is only used for writeback of CODE pages to memory. So there's no value in keeping the dcache lines around. Infact it is risky as a writeback on natural eviction under pressure can cause un-needed writeback with weird issues on aliasing dcache configurations.
