Subject: [PATCH 23/30] misc: mic: scif: scif_dma: Fix a couple of kerneldoc issues

Firstly demote scif_rma_destroy_tcw()'s header to a standard
comment as no attempt has been made to document any of the
function arguments.  Secondly, provide missing description
for 'prot' for scif_register_temp().

Fixes the following W=1 kernel build warnings:

 drivers/misc/mic/scif/scif_dma.c:110: warning: Function parameter or member 'mmn' not described in '__scif_rma_destroy_tcw'
 drivers/misc/mic/scif/scif_dma.c:110: warning: Function parameter or member 'start' not described in '__scif_rma_destroy_tcw'
 drivers/misc/mic/scif/scif_dma.c:110: warning: Function parameter or member 'len' not described in '__scif_rma_destroy_tcw'
 drivers/misc/mic/scif/scif_dma.c:344: warning: Function parameter or member 'prot' not described in 'scif_register_temp'
