This patch truly enables CONFIG_MMC_BLOCK_BOUNCE feature by setting the hw/phys
segs to 1 without which the feature is not exploited as large/bounce buffers of
size 64KB are not used for any of read/write transaction. Without this patch,
smaller buffers are used whose sizes vary from 512 Bytes to 32KB. In my testing
with a SD Extreme III high speed 2GB SD card using FAT file system performance
improvement of about 10% for write and 40% for reads has been observed. Write
and Read speed without this patch was 5.2Mbytes/sec and 6.5Mbytes/sec
respectively whereas write and read performance with this patch has jumped to
5.9Mbytes/sec and 9MBytes/sec, respectively.
