Subject: [PATCH] clocksource, acpi_pm.c: put acpi_pm_read_slow() under
CONFIG_PCI
acpi_pm_read_slow() is only used when CONFIG_PCI=y, so move the definition
inside the ifdef.
Otherwise this causes a "defined but not used" warning when building with
CONFIG_ACPI=y and CONFIG_PCI=n (that's not supported yet, but it could
be).
