[PATCH 4/5] ARM: i.MX51 babbage: use mc13xxx_register_callback to initialize PMIC

[Sascha Hauer <s.hauer@pengutronix.de>]

This makes sure the PMIC is initialized once it's available. Move the
initcall to coredevice_initcall to make sure we initialize the PMIC
before the FEC driver is initialized. The ethernet phy needs vgen3
enabled in the PMIC initialization.
