[ARM] remove memzero()
As suggested by Andrew Morton, remove memzero() - it's not supported on other architectures so use of it is a potential build breaking bug. Since the compiler optimizes memset(x,0,n) to __memzero() perfectly well, we don't miss out on the underlying benefits of memzero(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
