[PATCH] Documentation: ACPI: EINJ: Update stale driver source reference

[PATCH] Documentation: ACPI: EINJ: Update stale driver source reference

[Prabhakar Pujeri]

The EINJ implementation was split when CXL protocol error injection
support landed: einj-core.c holds the core logic, einj-cxl.c the
CXL-specific part, and apei-internal.h the shared plumbing. The old
drivers/acpi/apei/einj.c does not exist anymore, so the documentation
points readers at a nonexistent file.

Point them at the actual files instead.

+Anyway, you get the idea, if there's doubt just take a look at the code:
+drivers/acpi/apei/einj-core.c holds the core logic, while CXL-specific
+handling lives in drivers/acpi/apei/einj-cxl.c and the shared plumbing
+in drivers/acpi/apei/apei-internal.h.
 
 An ACPI 5.0 BIOS may also allow vendor-specific errors to be injected.
 In this case a file named vendor will contain identifying information
