[PATCH v2 4/9] PM / ACPI: Split acpi_lpss_suspend_late|resume_early()

[Ulf Hansson <ulf.hansson@linaro.org>]

Move the code which is special to ACPI LPSS into separate functions. This
may clarify the code a bit, but the main purpose of this change, is instead
to prepare for additional changes on top. Ideally the following changes
should then become easier to review.
