Subject: x86/PCI: Make broadcom_postcore_init() check acpi_disabled

From: Rafael J. Wysocki <[email protected]>

commit ddec3bdee05b06f1dda20ded003c3e10e4184cab upstream.

acpi_os_get_root_pointer() may return a valid address even if acpi_disabled is set, but the host bridge information from the ACPI tables is not going to be used in that case and the Broadcom host bridge initialization should not be skipped then, So make broadcom_postcore_init() check acpi_disabled too to avoid this issue.
