openrisc: don't printk() unconditionally

Browse Source 
Don't call printk() when CONFIG_PRINTK is not set.
Fixes the following build errors:

or1k-linux-ld: arch/openrisc/kernel/entry.o: in function `_external_irq_handler':
(.text+0x804): undefined reference to `printk'
(.text+0x804): relocation truncated to fit: R_OR1K_INSN_REL_26 against undefined symbol `printk'
