[PATCH 1/2] Documentation: syfs-class-firmware-attributes: Lenovo Opcode support

[Mark Pearson <markpearson@lenovo.com>]

Newer Lenovo BIOS's have an opcode GUID support interface which provides
 - improved password setting control
 - ability to set System, hard drive and NVMe passwords

Add the support for these new passwords, and the ability to select
user/master mode and the drive index.
