ARM: Remove __flush_icache_all() from __flush_dcache_page()
Both call sites for __flush_dcache_page() end up calling __flush_icache_all() themselves, so having __flush_dcache_page() do this as well is wasteful. Remove the duplicated icache flushing. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
