Subject: [PATCH] clocksource: nps: fix nps_timer_init return value

The CLOCKSOURCE_OF_DECLARE macro ensures that the type of the init
function matches the caller. In case of the new timer-nps driver,
it doesn't match, so we get a warning:

../drivers/clocksource/timer-nps.c:97:208: error: comparison of distinct pointer types lacks a cast [-Werror]
 CLOCKSOURCE_OF_DECLARE(ezchip_nps400_clksrc, ezchip,nps400-timer,

This changes the return type to match what the caller expects.
