Lars-Peter Clausen 1d210386f6 MIPS: jz4740: Fix section mismatch in prom.c
This patch fixes the following section mismatch:

	WARNING: arch/mips/built-in.o(.text+0xc): Section mismatch in reference from the
	function jz4740_init_cmdline() to the variable .init.data:arcs_cmdline

While were at it, make jz4740_init_cmdline static as well.
