ACPI: simplify deferred execution path
We had two functions, acpi_os_execute_deferred() and
acpi_os_execute_hp_deferred() that differed only in that the
latter did acpi_os_wait_events_complete(NULL) before executing
the deferred function.
This patch consolidates those two functions and uses a flag in
the struct acpi_os_dpc to determine whether to do the wait.
