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.


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.
