Subject: [PATCH v11 02/23] CXL/AER: Remove CONFIG_PCIEAER_CXL and replace with CONFIG_CXL_RAS

CXL RAS compilation is enabled using CONFIG_CXL_RAS while the AER CXL logic
uses CONFIG_PCIEAER_CXL. The 2 share the same dependencies and can be
combined. The 2 kernel configs are unnecessary and are problematic for the
user because of the duplication. Replace occurrences of CONFIG_PCIEAER_CXL
to be CONFIG_CXL_RAS.

Update the CONFIG_CXL_RAS Kconfig definition to include dependencies 'PCIEAER
&& CXL_PCI' taken from the CONFIG_PCIEAER_CXL definition.

Remove the Kconfig CONFIG_PCIEAER_CXL definition.
