LoongArch: Align ACPI structures if ARCH_STRICT_ALIGN enabled

LoongArch: Align ACPI structures if ARCH_STRICT_ALIGN enabled

commit a9d13433fe17be0e867e51e71a1acd2731fbef8d upstream.

ARCH_STRICT_ALIGN is used for hardware without UAL, now it only control
the -mstrict-align flag. However, ACPI structures are packed by default
so will cause unaligned accesses.

To avoid this, define ACPI_MISALIGNMENT_NOT_SUPPORTED in asm/acenv.h to
align ACPI structures if ARCH_STRICT_ALIGN enabled.
