Subject: [PATCH v5 2/7] mips: remove unused macros

Remove NR_syscalls from asm/unistd.h as there is no
users to use NR_syscalls macro in mips kernel.

Remove __NR_Linux_syscalls from uapi/asm/unistd.h as
there is no users to use NR_syscalls macro in mips
kernel.

MAX_SYSCALL_NO can also remove as there is commit
2957c9e61ee9 ("[MIPS] IRIX: Goodbye and thanks for
all the fish"), eight years ago.
