9df5081740 reset: zynqmp: Add reset driver support for versal
Add support for versal platform by adding "xlnx,versal-reset"
compatible string in zynqmp-reset driver. Reset numbering schema
for versal is not same as zynqmp, so nr_reset and reset_id are
set to zero. In case of assert/dessert, required device reset id
is sent from respective driver through struct reset_ctl.

0be4b0b651 reset: Return 0 if ops unimplemented and remove empty functions
In case the ops is not implemented, return 0 in the core right away.
This is better than having multiple copies of functions which just
return 0 in each reset driver. Drop all those empty functions.

3f123b7424 reset: zynqmp: Add reset controller for ZynqMP SoC
Add firmware based reset controller for Xilinx ZynqMP SoC to let other
drivers to call reset functions. Driver is only tested on Xilinx ZynqMP but
support for Xilinx Versal can be simply added. That's why reset_id and
nr_reset are assigned in probe folder.
Driver is inpired by driver from Linux kernel.
