i.MX fixes for 4.20, round 3: 

- A couple of fixes on imx7d-pico and imx7d-nitrogen7 boards to correct
    the description of the Wifi clock.
  - Change SW2ISO count to get a safer ARM LDO ramp-up time, so that
    different boards can be covered. This fixes the ARM LDO failure seen
    on some customer boards.
