The T-Head TH1520 SoC integrates a variety of clocks for its subsystems,
including the Application Processor (AP) and the Video Output (VO) [1].
Up until now, the T-Head clock driver only supported AP clocks.
Extend the driver to provide clock functionality for the VO subsystem.
At this stage, the focus is on implementing the VO clock gates, as these
are currently the most relevant and required components for enabling and
disabling the VO subsystem functionality. Future enhancements may
introduce additional VO-related clocks as necessary.

* clk-fixes:
clk: clk-loongson2: Fix the number count of clk provider
clk: mmp2: call pm_genpd_init() only after genpd.name is set
clk: sunxi-ng: a100: enable MMC clock reparenting
clk: clk-imx8mp-audiomix: fix function signature
clk: thead: Fix TH1520 emmc and shdci clock rate
Add the CLK_IGNORE_UNUSED flag to the vp-axi clock (CLK_VP_AXI) to avoid
depending on clk_ignore_unused in the cmdline. Without this fix, the
emmc-sdio clock (CLK_EMMC_SDIO) fails to work after vp-axi is disabled.
