[PATCH 1/2] arm64/acpi: panic when failed to init acpi table with acpi=force option

[Yeoreum Yun]

when the acpi=force option is used,
the system does not fall back to the device tree (DT).
If it fails to initialize the ACPI table, it cannot proceed further.
In such cases, the system should invoke panic() to avoid contradicting
the user's explicit intent, as failing or
proceeding with unintended behavior would violate their wishes.
