Kerneldoc expects arg descriptions to be in the format '@.*: '.  If either
the '@' or the ':' is omitted then kerneldoc complains that the description
is missing.  Add the missing ':' here and provide a new description for
'value'.

Fixes the following kernel build W=1 warnings:

 drivers/mmc/host/sdhci-of-arasan.c:1394: warning: Function parameter or member 'host' not described in 'sdhci_arasan_update_support64b'
 drivers/mmc/host/sdhci-of-arasan.c:1394: warning: Function parameter or member 'value' not described in 'sdhci_arasan_update_support64b'
 drivers/mmc/host/sdhci-msm.c:1887:6: warning: no previous prototype for ‘sdhci_msm_dump_vendor_regs’ [-Wmissing-prototypes]
