[PATCH V2 1/6] cxl: Remove unused values in bare-metal environment.

[Christophe Lombard]

The two fields pid and tid of the structure cxl_irq_info are only used
in the guest environment. To avoid confusion, it's not necessary
to fill the fields in the bare-metal environment.
The PSL Process and Thread Identification Register is only used when
attaching a dedicated process for PSL8 only.
