Only rt2800 subdriver of rt2x00 implement sta_add() and sta_remove(),
we do not need generic version of those.

This is a semi-automated conversion to change rt2800_register_read
to return the register contents instead of passing them by value,
resulting in much better object code. The majority of the patch
was done using:
sed -i 's:\(rt2800_register_read(.*, .*\), &\(.*\));:\2 = \1);:' \
's:\(rt2800_register_read_lock(.*, .*\), &\(.*\));:\2 = \1);:' \
drivers/net/wireless/ralink/rt2x00/rt2800lib.c
The function itself was modified manually along with the one remaining
multi-line caller that was not covered automatically and the indirect
reference.

This prepares the driver for changing all the 'read' register accessors
to return the value instead of passing it by reference. Since a lot
of them are used in callbacks, this takes care of the callbacks first,
adding a couple of helpers that will be removed again one at a time.

Basic support for MT7620 built-in wireless radio was added to
OpenWrt in r41441. It has seen some heavy cleaning and refactoring
since in order to match the Kernel's code quality standards.

If we do not match skb entry, provide tx status via nomatch procedure.
Currently in that case we do rt2x00lib_txdone_noinfo(TXDONE_NOINFO),
which actually assume that entry->skb was posted without retries and
provide rate saved in skb desc as successful. Patch changed that to
rate read from TX_STAT_FIFO, however still do not provide correct
number of retries.
On SoC/PCI devices we keep providing status via standard txdone
procedure, no change in those devices, though we should thing about it.

The rt2800_drv_data structure contains driver specific
information. Move the declaration into the rt2800lib.h
header which is a more logical place for it. Also fix
the comment style to avoid checkpatch warning.
The patch contains no functional changes, it is in
preparation for the next patch.

MAX_LEN_CFG_MAX_PSDU specify maximum transmitted by HW AMPDU length
(0 - 8kB, 1 - 16kB, 2 - 32kB, 3 - 64kB). Set this option according to
remote stations capabilities (based on HT ampdu_factor). However limit
the value based our hardware TX capabilities as some chips can not send
more than 16kB (factor 1). Limit for all chips is currently 32kB
(factor 2), but perhaps for some chips this could be increased
to 64kB by setting drv_data->max_psdu to 3.
Since MAX_LEN_CFG_MAX_PSDU is global setting, on multi stations modes
(AP, IBSS, mesh) we limit according to less capable remote STA. We can
not set bigger value to speed up communication with some stations and
do not break communication with slow stations.

Currently mac80211 does not inform the driver of the session
block ack timeout when starting a rx aggregation session.
Drivers that manage the reorder buffer need to know this
parameter.
Seeing that there are now too many arguments for the
drv_ampdu_action() function, wrap them inside a structure.
