clk: meson: Fix GXL HDMI PLL fractional bits width
[ Upstream commit 21310c39ec01e82ef3ef9bf8ac385b53ccdc158c ]
The GXL Documentation specifies 12 bits for the Fractional bit field,
bit the last bits have a different purpose that we cannot handle right
now, so update the bitwidth to have correct fractional calculations.
