[linux-yocto] [4.12][PATCH 18/19] ACPI / LPIT: Export lpit_read_residency_count_address()

[Liwei Song]

From: Srinivas Pandruvada <srinivas.pandruvada at linux.intel.com>

commit 9383bbadfe29fe8319e2245b75a508db9abd7b87 upstream.

Export lpit_read_residency_count_address(), so that it can be used from
drivers built as module. With the recent changes, the builtin_pci
functionality of the intel_pmc_core driver is removed and now it can be
built as a module to read this exported interface to calculate the PMC base
address.
