regulator: Fixes for v4.6

A small collection of driver specific fixes for the regulator
subsysetem:

 - Fix handling of probe deferral for GPIO regulators.
 - Fix a typo in the module alias for DA9053.
 - Fix the definition of BUCK9 in the S2MPS11 driver.  This change looks
   larger than it is because an irregularity in the hardware means that
   the macro used to define bucks 6-10 needs duplicating and tweaking
   to have a separate macro for 9.
 - Fix a series of errors in the definitions of the LDOs the AXP20x
   regulators, some of which had always been present and some of which
   were introduced in the merge window.

A common simplified DT parsing code for regulators was introduced in
commit a0c7b164 ("regulator: of: Provide simplified DT parsing
method")

While at it also added RK8XX_DESC and RK8XX_DESC_SWITCH macros for the
regulator_desc struct initialization. This just makes the driver more compact.

The regulators set consists of 2 BUCKs and 2 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components. The ramp delay is configurable
for both BUCKs.

Pull power management and ACPI fixes from Rafael Wysocki:
 "Fixes for problems introduced or discovered recently (intel_pstate,
  sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework,
  generic device properties framework) and one fix for a hotplug-related
  deadlock in ACPICA that's been there forever, but is nasty enough.

  Specifics:

   - Fix for a recent regression in the intel_pstate driver causing it
     to fail to restore the HWP (HW-managed P-states) configuration of
     the boot CPU after suspend-to-RAM (Rafael Wysocki).

   - Fix for two recent regressions in the intel_pstate driver, one that
     can trigger a divide by zero if the driver is accessed via sysfs
     before it manages to take the first sample and one causing it to
     fail to update a structure field used in a trace point, so the
     information coming from it is less useful (Rafael Wysocki).

   - Fix for a problem in the sti-cpufreq driver introduced during the
     4.5 cycle that causes it to break CPU PM in multi-platform kernels
     by registering cpufreq-dt (which subsequently doesn't work)
     unconditionally and preventing the driver that would actually work
     from registering (Sudeep Holla).

   - Stable-candidate fix for an ARM64 cpuidle issue causing idle state
     usage counters to be incorrectly updated for idle states that were
     not entered due to errors (James Morse).

   - Fix for a recently introduced issue in the OPP (Operating
     Performance Points) framework causing it to print bogus error
     messages for missing optional regulators (Viresh Kumar).

   - Fix for a recently introduced issue in the generic device
     properties framework that may cause it to attempt to dereferece and
     invalid pointer in some cases (Heikki Krogerus).

   - Fix for a deadlock in the ACPICA core that may be triggered by
     device (eg Thunderbolt) hotplug (Prarit Bhargava)"

Converting dt to platform data logic involves picking up information
that is unique per regulator, however we can improve readability of
the code by allocating and referencing pdata->reg_init[idx] once in
the loop.

While at it, use sizeof(*pointer) when allocating pointer. This allows
for structure name changes with minimal code change.

Do not load one entry beyond the end of the syscall table when the
syscall number of a traced process equals to __NR_Linux_syscalls.
Similar bug with regular processes was fixed by commit 3bb457af
("[PARISC] Fix bug when syscall nr is __NR_Linux_syscalls").

This bug was found by strace test suite.
