Summary
clocksource/drivers/cadence-ttc: Fix memory leak in ttc_timer_probe
Details

In the Linux kernel, the following vulnerability has been resolved:

clocksource/drivers/cadence-ttc: Fix memory leak in ttctimerprobe

Smatch reports: drivers/clocksource/timer-cadence-ttc.c:529 ttctimerprobe() warn: 'timerbaseaddr' from ofiomap() not released on lines: 498,508,516.

timerbaseaddr may have the problem of not being released after use, I replaced it with the devmofiomap() function and added the clkput() function to cleanup the "clkce" and "clkcs".
