[MIPS] fix sparse warning about setup_early_printk()
This patch fixes the following sparse warning:
<<<<<<<<
arch/mips/kernel/early_printk.c:35:13: warning: symbol 'setup_early_printk'
was not declared. Should it be static?
<<<<<<<<
The fix is to define a prototype of the setup_early_printk() function and
to include the appropriate header into arch/mips/kernel/early_printk.c.
[Ralf: Sorted includes again]
