clk: meson-gxbb: Add GXL/GXM GP0 Variant

Browse Source 
The clock tree in the Amlogic GXBB and GXL/GXM SoCs is shared, but the GXL/GXM
SoCs embeds a different GP0 PLL, and needs different parameters with a vendor
provided reduced rate table.

This patch adds the GXL GP0 variant, and adds a GXL DT compatible in order
to use the GXL GP0 PLL instead of the GXBB specific one.
