Kevin Hao fa25eba699 mmc: cavium: Set the correct dma max segment size for mmc_host 
We have set the mmc_host.max_seg_size to 8M, but the dma max segment
size of PCI device is set to 64K by default in function pci_device_add().
The mmc_host.max_seg_size is used to set the max segment size of
the blk queue. Then this mismatch will trigger a calltrace like below
when a bigger than 64K segment request arrives at mmc dev. So we should
consider the limitation of the cvm_mmc_host when setting the
mmc_host.max_seg_size.
