  PM / Domains: defer dev_pm_domain_set() until genpd->attach_dev succeeds if present

If the genpd->attach_dev or genpd->power_on fails, genpd_dev_pm_attach
may return -EPROBE_DEFER initially. However genpd_alloc_dev_data sets
the PM domain for the device unconditionally.

When subsequent attempts are made to call genpd_dev_pm_attach, it may
return -EEXISTS checking dev->pm_domain without re-attempting to call
attach_dev or power_on.

platform_drv_probe then attempts to call drv->probe as the return value
-EEXIST != -EPROBE_DEFER, which may end up in a situation where the
device is accessed without it's power domain switched on.

Pull more power management updates from Rafael Wysocki:
 "These revert one recent change in the generic power domains
  framework, fix a recently introduced build issue in there and
  constify attribute_group structures in some places.

  Specifics:

   - Revert a recent change in the generic power domains (genpd)
     framework that led to regressions and turned out the be misguided
     (Rafael Wysocki).

   - Fix a recently introduced build issue in the generic power domains
     (genpd) framework (Arnd Bergmann).

   - Constify attribute_group structures in the PM core, the cpufreq
     stats code and in intel_pstate (Arvind Yadav)"

Pull ARM SoC driver updates from Arnd Bergmann:
 "New SoC specific drivers:

   - NVIDIA Tegra PM Domain support for newer SoCs (Tegra186 and later)
     based on the "BPMP" firmware

   - Clocksource and system controller drivers for the newly added
     Action Semi platforms (both arm and arm64).

  Reset subsystem, merged through arm-soc by tradition:

   - New drivers for Altera Stratix10, TI Keystone and Cortina Gemini
     SoCs

   - Various subsystem-wide cleanups

  Updates for existing SoC-specific drivers

   - TI GPMC (General Purpose Memory Controller)

   - Mediatek "scpsys" system controller support for MT6797

   - Broadcom "brcmstb_gisb" bus arbitrer

   - ARM SCPI firmware

   - Renesas "SYSC" system controller

  One more driver update was submitted for the Freescale/NXP DPAA data
  path acceleration that has previously been used on PowerPC chips. I
  ended up postponing the merge until some API questions for its unusual
  MMIO access are resolved"

When CONFIG_PM_SLEEP is disabled, we don't have a pm_genpd_poweroff_noirq
function definition:

drivers/base/power/domain.c: In function 'pm_genpd_init':
drivers/base/power/domain.c:1549:37: error: 'pm_genpd_poweroff_noirq' undeclared (first use in this function); did you mean 'genpd_power_off_unused'?

This adds another NULL definition for it, just like we already have
for the other _noirq handlers.
