Subject: [PATCH] clk: qcom: ipq8074: fix PCI-E clock oops
Fix PCI-E clock related kernel oops that are causes by missing
parent_names.
Without the use of parent_names kernel will panic on
clk_core_get_parent_by_index() due to a NULL pointer.
Without this earlycon is needed to even catch the OOPS as it will reset
the board before serial is initialized.
Fixes: f0cfcf1ade20 ("clk: qcom: ipq8074: Add missing clocks for pcie")
