When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

Add debugfs to send host command in mvm and fmac op modes.
Allows to send host command at runtime via send_hcmd debugfs file.
The command is received as a string that represents hex values.
The struct of the command is as follows:
[cmd_id][flags][length][data]
cmd_id and flags are 8 chars long each.
length is 4 chars long.
data is length * 2 chars long.

The Free Software Foundation address is superfluous and causes
checkpatch to issue a warning when present. Remove all paragraphs
with FSF's address to prevent that.

The user can validate what was written to the file by reading it,
and check what is the default value before changing it.

Upon first calling read() on a debugfs file, invoke
iwl_dbgfs_##name##_read and store the response buffer on the heap, so
subsequent read() calls don't need to invoke said function again.
This is done because cat etc will call read() repeatedly until EOF is
reached (or read() returns 0), which in the current implementation will
cause said function to be invoked multiple times.
With the current implementation this can also cause buggy behavior in
some weird edge cases where the first invocation returns a string of
length n, and the second of length m>n: The last m-n characters of
the second invocation will be printed to screen.

These functions are not debugfs functions so they should be in dbg.h
instad in debugfs.h.

Prefer the direct use of octal for permissions.
Done with checkpatch -f --types=SYMBOLIC_PERMS --fix-inplace
and some typing.
Miscellanea:
o Whitespace neatening around these conversions.

For sync we send a marker cmd every <defined throughout debugfs> seconds.
The trigger for getting gp2 clock values from the FW is set by
writing to debugfs a periodic time in seconds,
if value zero is written, only one request would be sent
and the timer would be canceled.
Also added a small infrastructure for debugfs runtime code.
