clocksource, acpi_pm.c: put acpi_pm_read_slow() under CONFIG_PCI

Browse source 
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).
