clocksource/drivers/clps711x: Do not unmap clocksource MMIO
clps711x_clksrc_init() stores the timer base address in the static tcd
pointer and registers it as both the clocksource MMIO address and the
sched_clock read address.
The clocksource init path must therefore keep the mapping alive after
clps711x_timer_init() returns. However, the shared unmap_io exit path is
also reached after successful clocksource registration, so the MMIO
mapping is torn down while the clocksource and sched_clock readers may
still access it.
Return directly after successful clocksource registration and leave the
mapping alive for the registered readers. Keep the unmap_io path for the
error paths and for the clockevent init path.
