[PATCH] staging: most: Eliminate symbolic permissions usage

[Jason Litzinger]

Fix checkpatch warnings regarding the use of symbolic permissions.

Where the MOST_CHANNEL_ATTR macro is used, convert to octal permissions
over symbolic.

Where _ATTR is used directly, replace with _ATTR_RW/_ATTR_WO and
update the show/store function names appropriately.
