Update the list with supported Arcturus chips, but disable for now until
final list is confirmed.
Ideally we can poll atombios for FRU support, instead of maintaining
this list of chips, but this will enable serial number reading for
supported ASICs for the time-being.

drm/amdgpu: Re-enable FRU check for most models v52020-04-09T14:43:17ZKent Russellkent.russell@amd.com2020-04-03T14:42:21Zurn:sha1:1ea2b260eb6306b31dd6a932693519dd35da3774
There is at least 1 VG20 DID that does not have an FRU, and trying to read
that will cause a hang. For now, explicitly support reading the FRU for
Arcturus and for the WKS VG20 DIDs, and skip for everything else.
This re-enables serial number reporting for server cards
v2: Add ASIC check
v3: Don't default to true for pre-VG20
v4: Use DID instead of parsing the VBIOS
v5: Sqaush in overflow warning fix

Ensure that when we memcpy, we don't end up copying more data than
the struct supports. For now, this is 16 characters for product number
and serial number, and 32 chars for product name

drm/amdgpu: Enable reading FRU chip via I2C v32020-04-01T18:44:41ZKent Russellkent.russell@amd.com2020-03-13T13:21:55Zurn:sha1:bd607166af7fe31f8d8e9c575f4561a4b56b9f24
Allow for reading of information like manufacturer, product number
and serial number from the FRU chip. Report the serial number as
the new sysfs file serial_number. Note that this only works on
server cards, as consumer cards do not feature the FRU chip, which
contains this information.
v2: Add documentation to amdgpu.rst, add helper functions,
rename functions for consistency, fix bad starting offset
v3: Remove testing definitions
