[PATCH] ARM: SDEI: allow sdei initialization even no APCI support

[PATCH] ARM: SDEI: allow sdei initialization even no APCI support

[Schspa Shi]

The initialization of SDEI is forcibly bound by ACPI. This Patch allows to
continue to support the initialization of SDEI without starting ACPI.

Fixes: dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in apci_init()")
