drm/meson: Switch PLL to 5.94GHz base for 297Mhz pixel clock
On Amlogic G12A SoC, the 2,97GHz PLL frequency is not stable enough
to provide a correct 297MHz pixel clock, so switch the PLL base
frequency with a /2 OD when the 297MHz pixel clock is requested.
This solves the issue on G12A and also works fine on GXBB, GXL & GXM.
