Subject: [RESEND v13 05/25] cxl: Remove CXL VH handling in CONFIG_PCIEAER_CXL conditional blocks from core/pci.c
From: Dave Jiang <dave.jiang@...el.com>
Create new config CONFIG_CXL_RAS and put all CXL RAS items behind the
config. The config will depend on CPER and PCIE AER to build. Move the
related VH RAS code from core/pci.c to core/ras.c.
Restricted CXL host (RCH) RAS functions will be moved in a future patch.

Changes in v11->v12:
- None
Changes in v10->v11:
- New patch
- Updated by Terry Bowman to use (ACPI_APEI_GHES && PCIEAER_CXL) dependency
in Kconfig. Otherwise checks will be reauired for CONFIG_PCIEAER because
AER driver functions are called.
