[PATCH] regulator: core: Use postcore_initcall(regulator_init_complete)

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>

Commit 22ceeee1 (pwm-backlight: Add power supply support) introduced the usage
of regulator API into the pwm backlight driver and caused a regression on some 
boards like mx28evk and mx6qsabresd, resulting in blank display output:

pwm-backlight backlight.18: dummy supplies not allowed

Calling regulator_init_complete via late_initcall can be too 'late' for the 
regulator to be available for the pwm backlight driver.

Call regulator_init_complete with postcore_initcall level instead.
