Subject: [PATCH 1/4] PM: Drop the SET_PM_RUNTIME_PM_OPS() macro

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

The SET_PM_RUNTIME_PM_OPS() and SET_RUNTIME_PM_OPS() macros are
identical except that one of them is not empty for CONFIG_PM set,
while the other one is not empty for CONFIG_PM_RUNTIME set,
respectively.

However, after commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if
PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so one
of these macros is now redundant.

For this reason, drop SET_PM_RUNTIME_PM_OPS() and replace it with
SET_RUNTIME_PM_OPS() everywhere.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
