[PATCH] mips: Align prom_putchar() signatures with header

[Alexander Sverdlin <alexander.sverdlin@xxxxxxxxx>]

Fix a bunch of similar build failures:

 arch/mips/ath25/early_printk.c:29:6: error: conflicting types for 'prom_putchar'
    void prom_putchar(unsigned char ch)
         ^~~~~~~~~~~~
   In file included from arch/mips/ath25/early_printk.c:12:0:
   arch/mips/include/asm/setup.h:8:13: note: previous declaration of 'prom_putchar' was here
    extern void prom_putchar(char);
                ^~~~~~~~~~~~

Fixes: 112045c520 ("mips: unify prom_putchar() declarations")
