U-Boot does not have system calls (the services it exposes to standalone commands use a different mechanism), so the syscall handler is dead code. It's also broken code, as it assumes it is located at 0xc00 -- while even before the patch to stop relocating exception vectors to 0, U-Boot had the syscall at 0x900.
The critical and machine check return paths are never called -- the regular exception return path is used instead, which works because xSRR0/1 have already been saved and can be restored via the regular SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck inside another exception prolog/epilog).
Also remove a few other small unused functions.
