Currently xilinx sdhci driver is using zynqmp_mmio_write() to set tapdelay values and DLL resets. Continue to use this for SPL and mini U-Boot where U-Boot will be executed at EL3 level. Use firmware call xilinx_pm_request() using appropriate arguments to set input/output tapdelays and also for DLL resets in regular flow(EL2). Host driver should explicitly request DLL reset before ITAP (assert DLL) and after OTAP (release DLL) to avoid issues in some cases. Also handle error return where possible.
