[RESEND PATCH v2 0/4] add mipi_csi_xx gate clocks for SC9863A

[Chunyan Zhang <zhang.lyra@gmail.com>]

From: Chunyan Zhang <chunyan.zhang@unisoc.com>

mipi_csi_xx clocks are used by camera sensors. These clocks cannot be
accessed (even read) if their parent gate clock is disabled. So this
patchset also add a check to parent clocks when reading these gate
clocks which marked with the specific flag (SPRD_GATE_NON_AON).
