Subject: [PATCH 1/3] ACPI: Cleanup acpi_initrd_override declaration and remove ifdefs

Move the acpi_initrd_override() declaration out of CONFIG_ACPI area so that
acpi_initrd_override is also defined if CONFIG_ACPI is not defined.

Move the acpi_initrd_override() call into reserve_initrd() inside the
CONFIG_BLK_DEV_INITRD block.

Now ifdefs around the call in setup.c can be removed.

Cleanup only, no functional change.
