rtc-mxc: multiple fixes in rtc-mxc probe method

On exit paths in mxc_rtc_probe() method some resources are not freed
correctly.

This patch fixes:
* unrequested memory region containing imx RTC registers
* iounmap() isn't called on exit_free_pdata branch
* clock get rate is called for freed clock source
* clock isn't disabled on exit_put_clk branch

To simplify the fix managed device resources are used.
