[PATCH platform-next 9/9] Documentation/ABI: Add new attributes for mlxreg-io sysfs interfaces

[Vadim Pasternak <vadimp@nvidia.com>]

Add documentation for the new attributes:
- "asic2_health" - health of 2-nd ASIC for system equipped with two ASICs.
- "asic_reset" and "asic2_reset" - ASICs reset control.
- "comm_chnl_ready" - communication channel indication to remote end (BMC).
- "config3" - indication of system minor BOM changes.
