Robert Marko bf8f5182b8 clk: qcom: ipq8074: fix PCI-E clock oops 
Fix PCI-E clock related kernel oops that are caused by a missing clock
parent.

pcie0_rchng_clk_src has num_parents set to 2 but only one parent is
actually set via parent_hws, it should also have "XO" defined.
This will cause the kernel to panic on a NULL pointer in
clk_core_get_parent_by_index().

So, to fix this utilize clk_parent_data to provide gcc_xo_gpll0 parent
data.
Since there is already an existing static const char * const gcc_xo_gpll0[]
used to provide the same parents via parent_names convert those users to
clk_parent_data as well.

Without this earlycon is needed to even catch the OOPS as it will reset
the board before serial is initialized with the following:
