MIPS: powertv: Drop SYS_HAS_EARLY_PRINTK

PowerTV does not provide a prom_putchar function needed for early
printk so remove this symbol for this platform.

Fixes the following problem when EARLY_PRINTK is enabled for powertv:

arch/mips/kernel/early_printk.c:24: undefined reference to `prom_putchar'
arch/mips/kernel/early_printk.c:23: undefined reference to `prom_putchar'
