ASoC: Updates for v4.9 

Apart from the cleanups done by Morimoto-san this has very much been a
 driver focused release with very little generic change:
 
  - A big factoring out of the simple-card code to allow it to be shared
    more with the rcar generic card from Kuninori Morimoto.
  - Removal of some operations duplicated on the CODEC level, again by
    Kuninori Morimoto.
  - Lots more machine support for x86 systems.
  - New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663.

The flags argument should normally be set to 0, but can be used to pass the
PCI_IRQ_NOMSI and PCI_IRQ_NOMSIX flag in case a device claims to support
MSI or MSI-X, but the support is broken, or to pass PCI_IRQ_NOLEGACY in

By default this function will spread the interrupts around the available

The flags argument is used to specify which type of interrupt can be used
by the device and the driver (PCI_IRQ_LEGACY, PCI_IRQ_MSI, PCI_IRQ_MSIX).
A convenient short-hand (PCI_IRQ_ALL_TYPES) is also available to ask for
any possible kind of interrupt. If the PCI_IRQ_AFFINITY flag is set,
pci_alloc_irq_vectors() will spread the interrupts around the available CPUs.

The platform device problem
---------------------------
DSA is currently implemented as a platform device driver which is far from ideal
as was discussed in this thread:
http://permalink.gmane.org/gmane.linux.network/329848
This basically prevents the device driver model to be properly used and applied,
and support non-MDIO, non-MMIO Ethernet connected switches.
Another problem with the platform device driver approach is that it prevents the
use of a modular switch drivers build due to a circular dependency, illustrated
here:
http://comments.gmane.org/gmane.linux.network/345803
Attempts of reworking this has been done here:

For best performance, an arch should use seccomp_phase1 and
seccomp_phase2 directly. It should call seccomp_phase1 for all
syscalls if TIF_SECCOMP is set, but seccomp_phase1 does not
need to be called from a ptrace-safe context. It must then
call seccomp_phase2 if seccomp_phase1 returns anything other
than SECCOMP_PHASE1_OK or SECCOMP_PHASE1_SKIP.
As an additional optimization, an arch may provide seccomp_data
