clocksource/drivers/clps711x: Fix resource leaks in error paths

commit cd32e596f02fc981674573402c1138f616df1728 upstream.

The current implementation of clps711x_timer_init() has multiple error
paths that directly return without releasing the base I/O memory mapped
via of_iomap(). Fix of_iomap leaks in error paths.

Fixes: 2a6a8e2d9004 ("clocksource/drivers/clps711x: Remove board support")
