Thanks for the patch. However, this goes exactly in the opposite
direction of commit dd640039e8de4135fd59d4d963487d1239d6fabe ("gpio:
mvebu: Remove initcall-based driver initialization"), which switched
from postcore_initcall() to module_platform_driver().

Can you describe which drivers registered at subsys_initcall() need
those GPIOs? We should be able to get around by using deferred probing.

Thanks,

Thomas
