[PATCH] mmc: zynq_sdhci: Dll reset only for ZynqMP platform

[Michal Simek]

From: Ashok Reddy Soma <ashok.reddy.soma at amd.com>

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.
