PCI: brcmstb: Set bus max burst size by chip type
The proper value of the parameter SCB_MAX_BURST_SIZE varies per chip. The
2711 family requires 128B whereas other devices can employ 512. The
assignment is complicated by the fact that the values for this two-bit
field have different meanings;
Value Type_Generic Type_7278
00 Reserved 128B
01 128B 256B
10 256B 512B
11 512B Reserved
