firmware: qcom: scm: Allow QSEECOM on HP EliteBook X G2q 14 AI

The HP EliteBook X G2q 14" Next Gen AI PC is a Snapdragon X2 Elite
(Glymur) laptop whose firmware exposes EFI variables through QSEECOM.
Add its board compatible to the QSEECOM allowlist so that EFI variable
access (efivarfs) works on this machine.

Without it the kernel reports "qseecom: untested machine, skipping" and
efivarfs is empty.
