Remove DLL properties which are not applicable for soft PHYs

what about sdhci1 node updates on
   - k3-am642-phyboard-electra-rdk.dts
   - k3-am642-tqma64xxl-mbax4xxl.dts



The same patch applies for this boards.


I will add for v3.




Also does this apply only for am64 and sdhci1 (and not sdhci0)?
In your v1 you are describing that only AM64x and AM62p devices have a DLL to update the drive strength. 
Trying to understand why only one of the interfaces gets updated.


This patch only applies for AM64x sdhci1 node, since sdhci1
is a soft PHY and does not have a DLL.
