Although qcom_snd_parse_of() tries to manage the of-node refcount,
there are still a few places that lead to the unblanced refcount in
the error code path.  Namely,

- for_each_child_of_node() needs to unreference the iterator node if
  aborting the loop in the middle,
- cpu, codec and platform node objects have to be unreferenced at each
  iteration,
- platform and codec node objects have to be referred before jumping
  to the error handling code that unreference them unconditionally.

This patch tries to address these by moving the assignment of platform
and codec node objects to the beginning of the loop and adding the
of_node_put() calls adequately.

The function simple_for_each_link() has a few missing places that
forgot unrefereing of-nodes after the use.  The main do-while loop
may abort when loop=0, and this leaves the node object still
referenced.  A similar leak is found in the error handling of NULL
codec that aborts the loop as well.  Last but not least, the inner
for_each_child_of_node() loop may abort in the middle, and this leaks
the refcount of the iterator node.

This patch addresses these missing refcount issues.

On some SoCs (e.g. Exynos5433) there are multiple "IIS multi audio
interfaces" and the driver will try to register there multiple times
same platform device for the secondary FIFO, which of course fails
miserably.  To fix this we derive the secondary platform device name
from the primary device name. The secondary device name will now
be <primary_dev_name>-sec instead of fixed "samsung-i2s-sec".

The fixed platform_device_id table entry is removed as the secondary
device name is now dynamic and device/driver matching is done through
driver_override.
