fix(stm32mp2-fdts): fix SDMMC slew rate

Browse source 
New slew rate applied.

SDMMC:
  - for SD card and eMMC:
    - clk at 2.
    - cmd and data at 1.
  - for Wifi
    - clk at 1.
    - cmd and data at 0.

SDMMC1:
 - for dk board:
   - clk at 2.
   - cmd and data at 1.
 - for eval board:
   - clk at 3.
   - cmd and data at 2.
