The 2.4.x branch mmc_lld driver does not calculate the card capacity (by reading the CSD on connect), and without this feature in the driver the disk IOCTL GET_SECTOR_COUNT can't be implemented and without it f_mkfs can't work.

I noticed the trunk has this feature implemented so I did a quick a minimal backport. See attached.

1- Patch for ChibiOS 2.4.x.
2- Patch for FatFS (to apply to the patched version that comes with ChibiOS).

    Too an old version for this kind of fixes, FatFS itself should be upgraded too.

    Not fixing, 2.6.0 will contain all the latest code.
