[PATCH v2 3/9] power: sequencing: pcie-m2: Improve PCI device ID check

[Manivannan Sadhasivam via B4 Relay <devnull+manivannan.sadhasivam.oss.qualcomm.com@kernel.org>]

From: Manivannan Sadhasivam <manivannan.sadhasivam@oss.qualcomm.com>

Instead of hardcoding the PCI device check, use pci_match_id() to check for
the known IDs using the pwrseq_m2_pci_ids[] array.

This makes adding support for new devices easier.
