[ Upstream commit 912b341585e302ee44fc5a2733f7bcf505e2c86f ]
Remove PSU EEPROM configuration for systems class equipped with Mellanox chip Spectrum and ATOM CPU - system types MSN274x. Till now all the systems from this class used few types of power units, all equipped with EEPROM device with address space two bytes. Thus, all these devices have been handled by EEPROM driver "24c02".
There is a new requirement is to support power unit replacement by "off the shelf" device, matching electrical required parameters. Such device can be equipped with different EEPROM type, which could be one byte address space addressing or even could be not equipped with EEPROM. In such case "24c02" will not work.

Please pick up eca6ba20f38c ("platform/x86: mlx-platform: remove an unused variable") everywhere that this patch was applied to avoid introducing a new clang warning.
