[PATCH 04/13] staging: most: use __ATTR_RO for the attribute value

[Christian Gromm <christian.gromm@microchip.com>]

From: Andrey Shvetsov <andrey.shvetsov@k2l.de>

This patch replaces the use of a macro create_inst_attribute for the
attribute value with a macro __ATTR_RO.

Additionally, this patch removes not anymore used macros MOST_INST_ATTR
and create_inst_attribute.
