This patch series updates/fixes below things:
 - Handle errors from tapdelay functions and return to set_delay()
 - Add ZynqMP firmware related enums which are used in sdhci driver
 - Replace mmio_write() with firmware call xilinx_pm_request()
 - Move tapdelay setting code from tap_delays.c to driver and remove
   tap_dealy.c and zynqmp_tap_delay.h
 - Change variable name from deviceid to node_id in couple of functions
   for consistancy
 - Add a workaround for sd card detect stable issue for Versal platforms
 - Use set_control_reg from sdhci.c

Changes in v2:
 - Split patch 1/7 to two patches, one for zynq_sdhci and other one
   for sdhci
 - This is the second patch that has been split from 1/7
 - This covers changes for sdhci driver separately
 - Added a debug print in case of error from set_delay()
 - Added comment for why 1ms delay is needed between DLL assert and
 release
 - Remove mmc->dev->seq_ and use priv->deviceid instead
 - Changed return error from -EIO to -ETIMEDOUT in arasan_sdhci_probe()
   in card detect state stable workaround
