phy: mediatek: phy-mtk-hdmi-mt8195: Fix PLL calc divisor overflow
When trying to calculate a PLL rate for target display resolutions
above 2560x1440, 24bpp, 30Hz, the pixel clock value will be more
than 32-bits long but the division to finally calculate the digital
clock divider is being done with div_u64(), which expects a 32bit
unsigned divisor.
Fix the overflow by using div64_u64() instead.
