arm64: zynqmp: Enable smmu again

Now that, PM support has been added to the SMMU
driver, enable it back by default.

Following issues were observed with SMMU earlier,
 - After suspend/resume with FPD off,all peripherals
   registered with SMMU are failed to work.This issue
   has been resoved now.
 - SATA device detection is failed. This issue still
   persist.

This reverts commit 223c3aa24a63bb837169d7253fac666965383934.
