Add the HE extended element IDs and the definitions for the
HE 6 GHz band capabilities element, from Draft 5.0.

While at it, fix the required length using sizeof() the new

The 6GHz band does not have regulatory approval yet, but things are
moving forward. However, that has led to a change in the channelization
of the 6GHz band which has been accepted in the 11ax specification. It
also fixes a missing MHZ_TO_KHZ() macro for 6GHz channels while at it.
This change is primarily thrown in to discuss how to deal with it.
I noticed ath11k adding 6G support with old channelization and ditto
for iw. It probably involves changes in hostapd as well.

The updates to change to kHz frequencies and the 6 GHz
additions evidently overlapped (or rather, I didn't see
it when applying the latter), so the 6 GHz is broken.

Originally the match arms are ordered by model release date, however
the LOONGSON_64R cores are even more reduced capability-wise. So put
them at top of the switch block.

The point is to allow userspace to probe for CPUCFG without possibly
triggering invalid instructions. In addition to that, future Loongson
feature bits could all be stuffed into CPUCFG bit fields (or "leaves"
in x86-speak) if Loongson does not make mistakes, so ELF HWCAP bits are
conserved.
Userspace can determine native CPUCFG availability by checking the LCSRP
(Loongson CSR Present) bit in CPUCFG output after seeing CPUCFG bit in
HWCAP. Native CPUCFG always sets the LCSRP bit, as CPUCFG is part of the
Loongson CSR ASE, while the emulation intentionally leaves this bit
clear.
The other existing Loongson-specific HWCAP bits are, to my best
knowledge, unused, as
(1) they are fairly recent additions,
(2) Loongson never back-ported the patch into their kernel fork, and
(3) Loongson's existing installed base rarely upgrade, if ever;
However, they are still considered userspace ABI, hence unfortunately
unremovable. But hopefully at least we could stop adding new Loongson
HWCAP bits in the future.

NAND ECC modes (or providers) have their own enumeration but, unlike
their algorithms counterpart, there is no invalid or uninitialized
value to discriminate between an error and having chosen a no-ECC

This scheme has been introduced for the Davinci controller and means
that the OOB area must be read *before* the rest of the data. This has
nothing to do with the ECC in OOB placement as it could be understood
and most importantly, there is no point in having this function out of
the Davinci NAND controller driver. A DT property for this scheme has
been added but never used, even by the Davinci driver which only uses
this scheme to change the default nand_read_page().
Move the main read_page() helper into the Davinci driver and remove
the remaining boilerplate.

Many function calls are done this way:
if ((retval = func()) != 0)
return retval;
while we expect in the kernel function calls like:
retval = func();
if (retval)
return retval;

"retval" in ns_init_module for consistency, as it is only used in this
function.

Some functions are prefixed "nandsim_", others "ns_" and many are
simply not prefixed at all. Make this file consistent by prefixing all
functions by "ns_".
This is a mechanical change. Sometimes the line is a bit reworked as
well to fit the kernel coding style. For instance, there are several
places where displayed strings are cut. When one of this line is
changed because of the naming update, the two parts of the strings
gets concatenated.
