Different from MSM8916 which has only one a53pll/mux clock, MSM8939 gets
three for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache
Coherent Interconnect).  That said, a53pll/mux clock needs to be named
uniquely.  Append @unit-address of device node to the clock name, so
that a53pll/mux will be named like below on MSM8939.

  a53pll@b016000
  a53pll@b116000
  a53pll@b1d0000

  a53mux@b1d1000
  a53mux@b011000
  a53mux@b111000
