pci: pci-uclass: Dynamically allocate the PCI regions

Browse Source 
Instead of using a fixed length pre-allocated array of regions, this
patch moves to dynamically allocating the regions based on the number
of available regions plus the necessary regions for DRAM banks.

Since MAX_PCI_REGIONS is not needed any more, its removed completely
with this patch.
