phy: mediatek: rework the floating point comparisons to fixed point
gcc on aarch64 reports
drivers/phy/mediatek/phy-mtk-hdmi-mt8195.c: In function ‘mtk_hdmi_pll_set_rate’:
drivers/phy/mediatek/phy-mtk-hdmi-mt8195.c:240:52: error: ‘-mgeneral-regs-only’
is incompatible with the use of floating-point types
240 | else if (tmds_clk >= 54 * MEGA && tmds_clk < 148.35 * MEGA)
Floating point should not be used, so rework the floating point comparisons
to fixed point.
