arm64: zynqmp: Fix tcminit mode value based on argv

Browse source 
The RPU pytest introduced by commit e894c10c04
("test/py: zynqmp_rpu: Add test for loading RPU apps") expects
3rd parameter as string not a number that's why extend command
to actually handle both. The issue with existing code is that
when any non number string is passed hextoul returns 0. For
backward compatibility zynqmp tcminit 0/1 can be still used but
it is recommended to use strings instead.
