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.
