Instead of "open coding" DEVICE_ATTR, use the corresponding
helper macros DEVICE_ATTR_{RW,RO,WO} in amd64_edac.c
Some function names needed to be changed to match the device
conventions <foo>_show and <foo>_store, but the functionality
itself is unchanged.
The devices using EDAC_DCT_ATTR_SHOW() are left unchanged.

Changes in v2:
- Revert back the device name changes which broke
the kernel. These were using the macro EDAC_DCT_ATTR_SHOW()
to construct the show methods based on device name.
