Add dynamic configuration support for Xilinx ZynqMP which takes care of
configuring the SD secure space configuration registers using EEMI APIs,
performing SD reset assert and deassert.
High level sequence:
- Check for the PM dynamic configuration support, if no error proceed with
SD dynamic configurations(next steps) otherwise skip the dynamic
configuration.
- Put the SD Controller in reset.
- Configure SD Fixed configurations.
- Configure the SD Slot Type.
- Configure the BASE_CLOCK.
- Configure the 8-bit support.
- Bring the SD Controller out of reset.
- Wait for 1msec delay.

Can we get an Ack from xilinx folks?
Xilinx was acquired by AMD some time ago. This has been tested and reviewed internally already. But
