Documentation/ABI: Add new line card attributes for mlxreg-io sysfs interfaces
Add documentation for the new attributes for line cards: - CPLDs versioning. - Write protection control for 'nvram' devices. - Line card reset reasons. - Enabling burning of FPGA and CPLDs. - Enabling burning of FPGA and gearbox SPI flashes, - Enabling power of whole line card. - Enabling power of QSFP ports equipped on line card. - The maximum powered required for line card feeding. - Line card configuration Id.
