Gregory CLEMENT dc4910d9e9 ARM: mvebu: Fix kernel hang in mvebu_soc_id_init() when of_iomap failed 
When pci_base is accessed whereas it has not been properly mapped by
of_iomap() the kernel hang. The check of this pointer made an improper
use of IS_ERR() instead of comparing to NULL. This patch fix this
issue.
