[PATCH] drivers:edac: Use DEVICE_ATTR helper macros

From: Dwaipayan Ray
Date: Sun Jul 11 2021 - 03:34:00 EST


Instead of "open coding" DEVICE_ATTR, use the corresponding
helper macros DEVICE_ATTR_{RW,RO_WO}.

Some function names needed to be changed to match the device
conventions <foo>_show and <foo>_store, but the functionality
itself is unchanged.

Build tested only with CONFIG_EDAC_DEBUG=y
