Gabor Juhos a68ad4d892 MIPS: ath79: allow to use board specific pci_plat_dev_init functions 
Th current implementation causes NULL pointer dereference
if 'pci_data' is not set:

pci 0000:00:00.0: BAR 0: assigned [mem 0x10000000-0x1000ffff 64bit]
pci 0000:00:00.0: BAR 0: set to [mem 0x10000000-0x1000ffff 64bit] (PCI
address [0x10000000-0x1000ffff])
CPU 0 Unable to handle kernel paging request at virtual address 00000000, epc == 802daca0, ra == 802e78a4

This can be avoided by calling the 'ar724x_pci_add_data'
function from the board specific setup code. However it
makes no sense to use that function for every board,
especially when the board does not needs to set the
platform_data field of any PCI device.

The patch allows the board setup code to specify a board
specific function if that is required.
