Subject: [PATCH v3 2/5] ACPI/APEI: Remove static from apei_hest_parse()

From: leoliu-oc <leoliu-oc@...oxin.com>

Each dev with AER capability needs to call the apei_hest_parse function to
match and extract register values from HEST PCIe AER structures.
Therefore, remove static from apei_hest_parse() so that it can be called
in another file.
