dts: stm32mp1: clock tree update

- Add st,digbypass on clk_hse node (needed for board rev.C)
- MLAHB/AHB max frequency increased from 200 to 209MHz, with:
  - PLL3P set to 208.8MHz for MCU sub-system
  - PLL3Q set to 24.57MHz for 48kHz SAI/SPI2S
  - PLL3R set to 11.29MHz for 44.1kHz SAI/SPI2S
  - PLL4P set to 99MHz for SDMMC and SPDIFRX
  - PLL4Q set to 74.25MHz for EVAL board
