soc/mediatek: dsi: Increase pcw precision
When configuring MIPI DSI Tx, the value of pcw was calculated from data
rate in MHz, leading to loss of precision. This patch changes to use
data rate in Hz for the calculation so that the resulting value should
be consistent with the one in kernel (CL:1786327).
In addition, change the type of data rate to u32, and calculation of
data rate from pixel clock is changed to use DIV_ROUND_UP for
consistency with kernel (CL:1761843).
Also remove unused variable txdiv.
