linux-aspeed: Add devmem kernel parameter
From the kernel commit message:
For security reasons, some configuration needs to run without /dev/mem
but on some occasions, to debug HW for instance, it's still useful to
be able to reboot the system with access to physical memory.
Add a kernel parameter which activates the /dev/mem device only when
'mem.devmem' is enabled.
