xilinx: zynqmp: Add bootmenu support

Popup the bootmenu for 5 sec with default boot options to CC on AMD CCs and
default to SOM on others.
Users can anytime disable the bootmenu by setting the variable
enable_bootmenu=0 in zynqmp_kria.env or setup it up at run time and save
variables to NV memory.

The patch is also fixing issue created by commit 4c7363068651 ("cmd:
setexpr: fix no matching string in gsub return empty value") which has
changed return value from setexpr command (Before this commit when
matching string wasn't found command return 1 that's why was possible to
use with if).
