pci: fsl_pci_init: Dynamically allocate the PCI regions

Browse Source 
Commit e002474158 ("pci: pci-uclass: Dynamically allocate the PCI regions")
changes 'struct pci_controller'.regions from pre-allocated array of
regions to dynamically allocated, which unfortunately broken lots of
boards that still use the non-DM PCI driver.

This patch changes the non-DM fsl_pci_init driver to dynamically
allocate the regions, just like what's done in the pci uclass driver.
