[v2,0/2] clk: meson: g12a: add MIPI DSI Host Pixel Clock

This serie adss the MIPI DSI Host Pixel Clock used to feed the DSI pixel
clock to the DSI Host controller.

Unlike the AXG SoC, the DSI Pixel Clock has a supplementary mux, divider and gate
stage before feeding the pixel clock to the MIPI DSI Host controller.

Changes since v1 at [1]:
- switch g12a_mipi_dsi_pxclk_sel flags to CLK_SET_RATE_NO_REPARENT
- fix aligment of g12a_mipi_dsi_pxclk_div & g12a_mipi_dsi_pxclk parent_hws
