The EDAC drivers locally maintaining a statically defined
memory-controllers counter don't care much about the MC index assigned as
long as it's unique so the EDAC core perceives it. Convert these drivers
to be using the generic MC index allocation procedure recently added to
the EDAC core.
There are a bunch of reported randconfig failures now because of this,
something like:

Since below commit, address mapping for vmemmap has changed for Radix
MMU, where address mapping is stored in kernel page table itself,
instead of earlier used 'vmemmap_list'.
commit 368a0590d954 ("powerpc/book3s64/vmemmap: switch radix to use
a different vmemmap handling function")
CPU features can be determined in makedumpfile, using
'cur_cpu_spec.cpu_features'.
This provides more data to makedumpfile about the crashed system, and
can help in filtering the vmcore accordingly.

Then the machine driver will skip to call set_sysclk() and set_pll()

Implement the ASRC memory to memory function using
the v4l2 framework, user can use this function with
v4l2 ioctl interface.
User send the output and capture buffer to driver and
driver store the converted data to the capture buffer.
This feature can be shared by ASRC and EASRC drivers
Audio memory to memory virtual driver use video memory to memory
virtual driver vim2m.c as example. The main difference is
device type is VFL_TYPE_AUDIO and device cap type is V4L2_CAP_AUDIO_M2M.
The device_run function is a dummy function, which is simply
copy the data from input buffer to
The input clock and output clock may not be the accurate
rate as the sample rate, there is some drift, so the convert
ratio of i.MX ASRC module need to be changed according to
actual clock rate.
Add V4L2_CID_USER_IMX_ASRC_RATIO_MOD control for user to
adjust the ratio.

Audio signal processing has the requirement for memory to
memory similar as Video.
This patch is to add this support in v4l2 framework, defined
new buffer type V4L2_BUF_TYPE_AUDIO_CAPTURE and
V4L2_BUF_TYPE_AUDIO_OUTPUT, defined new format v4l2_audio_format
for audio case usage.
The created audio
Linear Pulse-Code Modulation is used to represent
audio samples in buffer, the samples for each channel
are interleaved.
