f5bc0157be platform/x86: think-lmi: add debug_cmd 
Many Lenovo BIOS's support the ability to send a debug command which
is useful for debugging and testing unreleased or early features.

Adding support for this feature as a module parameter.

95d429206c platform/x86: think-lmi: Add pending_reboot support 
The Think-lmi driver was missing pending_reboot support as it wasn't
available from the BIOS. Turns out this is really useful to have from
user space so implementing from a purely SW point of view.

Thanks to Mario Limonciello for guidance on how fwupd would use this.

The struct tlmi_pwd_setting display_name member is initialized,
but never read. Remove it and the TLMI_PWDTYPE_MAXLEN define.

While at it also remove some other unused [MAX]LEN defines.
