kernel: preserve bootloader command line on MIPS
Somewhere in the conversion of the MIPS architecture code to Device Tree usage, there's been a failure to keep the separate variables holding the kernel command line reconciled between the tree and the bootloader. This patch restores previous functionality that broke. Signed-off-by: Daniel Gimpelevich <daniel@gimpelevich.san-francisco.ca.us> SVN-Revision: 44030
