7805fa8d78 platform/mellanox: mlxreg-hotplug: Add check for negative adapter number

hotplug device.

c6acad68eb platform/mellanox: mlxreg-hotplug: Modify to use a regmap interface
Restructure mlxreg header for unification of hotplug item definitions.

Unify hotplug items to allow any kind of item (power controller, fan
eeprom, psu eeprom, asic health) in common way.

Use a hardware independent regmap interface, enabling the support of
hotplug events over programmable devices attached to different bus
types, such as I2C, LPC, or SPI. Add a device node to the
mlxreg_core_data structure.

1f976f6978 platform/x86: Move Mellanox platform hotplug driver to platform/mellanox
In preparation for making the hotplug driver build for different
architectures, move mlxcpld-hotplug.c to platform/mellanox and the
header to include/linux/platform_data as mlxreg.h to reflect the new
interface changes to come.

Replace references to CPLD with REG throughout the files, consistent
with the new name.
