Subject: [PATCH 06/15] mmc: host: atmel-mci: Provide 2 new and correct 1 existing property description

'sg_len' and 'dma_conf' are missing correct kerneldoc documentation and
'buf_phys_addr' was misspelled.  Correcting these issues fixes the
following W=1 kernel build issues:

 mmc/host/atmel-mci.c:352: warning: Function parameter or member 'sg_len' not described in 'atmel_mci'
 mmc/host/atmel-mci.c:352: warning: Function parameter or member 'buf_phys_addr' not described in 'atmel_mci'
 mmc/host/atmel-mci.c:352: warning: Function parameter or member 'dma_conf' not described in 'atmel_mci'
