This patch adds fw_passed_dtb to arch/mips/ralink to support
CONFIG_MIPS_RAW_APPENDED_DTB. Furthermore it adds a check that __dtb_start is
not the same address as __dtb_end.

Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied
the arguments from dtb to arcs_command_line to prevent the kernel from
overwriting them.
Since there is now an option to keep the dtb arguments, default to the
new option remove the "backup" to arcs_command_line in case of USE_OF is
enabled, except for those platforms that still take the bootloader
arguments or do not use any at all.

RT5350 relies on the bootloader setting up the memc correctly. On some boards
the setup is incorrect leading to 32 MB being available but only 16 MB being
recognized. Allow these boards to manually override the memory range.

'compatible' is used by strlen() in __of_device_is_compatible().
Ensure strings are always '\0' terminated.
'of_ids is not a structure in "include/uapi/*", so no need to initialize
it completly; using strlcpy() instead of strncpy() will do.
