arm64: zynqmp: Fix r5 mode for cpu release command
The cpu release command for r5 mode (lockstep/split) argument
accepts only string. But the zynqmp tcminit command accepts
string or number for r5 mode (lockstep/split or 0/1) argument.
To fix the r5 mode argument, the common argument (lockstep/split
or 0/1) is used across different u-boot commands. Use the strcmp()
instead of strncmp() to make uniform the r5 mode (lockstep/split
or 0/1) for the zynqmp tcminit and cpu release command.
