mmc: zynq_sdhci: Dll reset only for ZynqMP platform
Dll reset is needed only for ZynqMP platforms, add condition in tuning to call arasan_zynqmp_dll_reset() just for ZynqMP platforms. On other platforms like Versal NET, If this condition is not added, we see PLM error messages when dll reset smc is called.
