[ARM] 4694/1: IXP4xx: Update clockevent support for shutdown and resume
Add proper support for CLOCK_EVT_MODE_RESUME and in the process fix CLOCK_EVT_MODE_SHUTDOWN so that only the enable bits are toggled for both. Signed-off-by: Kevin Hilman <khilman@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
