[PATCH 4.9 102/175] openrisc: dont printk() unconditionally

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit 946e1052cdcc7e585ee5d1e72528ca49fb295243 ]

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'

Fixes: 9d02a4283e9c ("OpenRISC: Boot code")
