zynqmp: pm: Add LPD WDT clock to the pm_clock structure
This patch adds LPD WDT clock node to the pm_clock clocks structure list
so that LPD WDT can be used from Linux.
Also this patch removes the CLK_LPD_LSBUS from invalid clock list to
allow the registration of this clock to CCF framework as it is the
parent of LPD WDT.
