i.MX legacy board file changes for 4.9:

Browse Source 
It includes a patch series that moves registrations and initializations
 of all peripherals which are GPIO line consumers for all legacy boards
 from .init_machine to .init_late init level. This is needed to
 proactively prevent boot time issues on the legacy boards due to the
 deprioritized init level of the GPIO controller driver (set lower than
 IOMUX controller driver init level), which is shared among all i.MX
 SoCs.
