[U-Boot] [PATCH] dm: mmc: socfpga: fix MMC_OPS support

[Sylvain Lesne]

Now that CONFIG_BLK and CONFIG_MMC_OPS are enabled by default with
CONFIG_DM_MMC, the DWMMC driver on the socfpga platform fails at
runtime.

This adds the missing fields in the driver declaration.

Hi,

I might be missing something, but with the latest master, on a
socfpga board, I get the following failure:

U-Boot SPL 2016.11-rc2-00072-g869588d-dirty (Oct 24 2016 - 17:18:22)
drivers/ddr/altera/sequencer.c: Preparing to start memory calibration
drivers/ddr/altera/sequencer.c: CALIBRATION PASSED
drivers/ddr/altera/sequencer.c: Calibration complete

spl: partition error
MMC: block number 0xx exceeds max(0xx)
mmc_load_image_raw_sector: mmc block read error
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

After some digging, it seems that the socfpga_dw_mmc driver slipped 
through the cracks during some steps of the DM conversion, so I 
added the missing fields of the driver declaration, mimicking what's 
done in the other dw_mmc_* drivers, and it works on my board.

(Also, this is kind of unrelated, but it looks like the error 
message 'MMC: block number 0xx exceeds max(0xx)' has a formatting 
issue!)
