[U-Boot] [PATCH] mpc5200: digsy_mtc: fix detection of Coral-PA

A delay of approximately 250 ms after PCI bus reset in
pci_mpc5xxx_init() is needed to recognize the Coral-PA
controller on the graphic extention board.

To make it actually work another patch
"pci: move pcidelay code to new location just before PCI bus scan"
is also required. It has been submitted earlier [1] and there is
already some positive feedback.
