[POWERPC] ucc_geth: use rx-clock-name and tx-clock-name device tree properties
Updates the ucc_geth device driver to check the new rx-clock-name and tx-clock-name properties first. If present, it uses the new function qe_clock_source() to obtain the clock source. Otherwise, it checks the deprecated rx-clock and tx-clock properties. Update the device trees for 832x, 836x, and 8568 to contain the new property names only.
