drm/bridge: samsung-dsim: calculate porches in Hz
Calculating the byte_clk in kHz is imprecise for a hs_clock of 55687500
Hz, which may be used with a pixel clock of 74.25 MHz with mode
1920x1080-30.
Fix the calculation by using HZ instead of kHZ.
This requires to change the type to u64 to prevent overflows of the
integer type.
