rtc: zynqmp: Fix optional clock name property 

commit 2a388ff22d2cbfc5cbd628ef085bdcd3b7dc64f5 upstream.

Clock description in DT binding introduced by commit f69060c144
("dt-bindings: rtc: zynqmp: Add clock information") is talking about "rtc"
clock name but driver is checking "rtc_clk" name instead.
Because clock is optional property likely in was never handled properly by
the driver.

Fixes: 07dcc6f9c7 ("rtc: zynqmp: Add calibration set and get support")
