QE Microcode Initialization using qe_upload_microcode() does not work on
P1021 if the IRAM-Ready register is not set after the microcode upload. Add
a definition for the "I-RAM Ready" register and sets it upon microcode
upload completion.

There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.
Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

This is needed to avoid ugly #ifdefs in drivers. Also update fsl_qe_udc
driver so that now it doesn't define its own versions that cause build
breakage when the generic stubs are used.

It appears that QE shuts down on all MPC85xx CPUs (i.e. MPC8568 and
MPC8569) and thus needs reset upon resume.
So modify qe_alive_during_sleep() to account that.

For MPC8569 CPUs we'll need to reset QE after each suspend, so make
qe_reset() code path suitable for repeated invocation, that is:
- Don't initialize rheap structures if already initialized;
- Don't allocate muram for SDMA if already allocated, just reinitialize
registers with previously allocated muram offset;
- Remove __init attributes from qe_reset() and cpm_muram_init();

In some CPUs (i.e. MPC8569) QE shuts down completely during sleep,
drivers may want to know that to reinitialize registers and buffer
descriptors.
This patch implements qe_alive_during_sleep() helper function, so far
it just checks if MPC8569-compatible power management controller is
present, which is a sign that QE turns off during sleep.

The latest QE chip may have more Serial Number(SNUM)s of thread to use. We
will get the number of SNUMs from device tree by reading the new property
"fsl,qe-num-snums", and set 28 as the default number of SNUMs so that it is
compatible with the old QE chips' device trees which don't have this new
property. The macro QE_NUM_OF_SNUM is defined as the maximum number in QE
snum table which is 256.
Also we update the snum_init[] array with 18 more new SNUMs which are
confirmed to be useful on new chip.

With this API we're able to set a QE pin to the GPIO mode or a dedicated
peripheral function.
The API relies on the fact that QE gpio controllers are registered. If
they aren't, the API won't work (gracefully though).
There is one caveat though: if anybody occupied the node->data before us,
or overwrote it, then bad things will happen. Luckily this is all in the
platform code that we fully control, so this should never happen.
I could implement more checks (for example we could create a list of
successfully registered QE controllers, and compare the node->data in the
qe_pin_request()), but this is unneeded if nobody is going to do silly
things behind our back.

git mv include/asm-powerpc/* arch/powerpc/include/asm
Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly. Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
