[PATCH] frv: define MMU mode specific syscalls as 'cond_syscall' and clean up unneeded macros 

For some architectures, a few syscalls are not linked in noMMU mode.  In
that case, the MMU depending syscalls are needed to be defined as
'cond_syscall'.  For example, ARM architecture selectively links sys_mlock
by the mode configuration.

In case of FRV, it has been managed by #ifdef CONFIG_MMU macro in
arch/frv/kernel/entry.S.  However these conditional macros are just
duplicates if they were defined as cond_syscall.  Compilation test is done
with FRV toolchains for both of MMU and noMMU mode.
