Rx descriptors queue length is hardware specific. Current common default
value is no more than an accident. So move Rx descriptor queue setup to
platform PCIe backend in the same way as it is already done for Tx.

It is because 8192cu doesn't implement usb_cmd_send_packet(), and this
patch just frees the skb within the function to resolve memleak problem
by now. Since 8192cu doesn't turn on fwctrl_lps that needs to download
command packet for firmware via the function, applying this patch doesn't
affect driver behavior.

Hence remove errornous line 5281 to make the driver actually
execute the correct initialization routine for MT7620 chips.
As it was requested by Stanislaw Gruszka remove setting values of
MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
power-safe mode (which is disabled), hence we can drop setting it.
TX_PIN_CFG is set correctly in other functions, and as setting this
value breaks some devices, rather don't set it here during init, but
only modify it later on.

The LPS threshold was set to 2, means driver will leave LPS
mode if there is more than 2 frames TX/RX for every 2 seconds.
This makes driver enter/leave LPS frequently even if we just
"ping -i1" to the others.
Apparently we do not want to leave LPS mode if there is only
some background traffics or web surfing. By experiment, set
this to 50 is a more reasonable value to lower the over all

The checks to see if swing_table->n or swing_table->p are null are
redundant since n and p are arrays and can never be null if
swing_table is non-null. I believe these are redundant checks
and can be safely removed, especially the checks implies that these
are not arrays which can lead to confusion.

The FW info was printed everytime driver is powered on, such as
leaving IDLE state. It will flood the kernel log.
Move the FW info printing to callback when FW is loaded, so
that will only be printed once when device is probed.

The level of cckpd is from 0 to 4, and it is the index of
array pd_lvl[] and cs_lvl[]. However, the length of both arrays
are 4, which is smaller than the possible maximum input index.
Enumerate cck level to make sure the max level will not be wrong
if new level is added in future.

Driver just memset() rx_status to 0 before assigning rate indexes.
And driver could never hit the 'else' because the driver checks
if 'pkt_stat->rate >= DESC_RATEMCS0', so the 'else' statement can
be removed.
Also rearrange the if..else statements because DESC_RATEMCS0 is
actually larger than DESC_RATE1M ~ DESC_RATE54M, move the check
of 'pkt_stat->rate >= DESC_RATEMCS0' to the last to keep an
increasing order.

The API was reduced to include only knowledge currently needed by the
FW scan logic, the rest is legacy. Support the new, reduced version.
Using the old API with newer firmwares (starting from
iwlwifi-*-50.ucode, which implements and requires the new API version)
causes an assertion failure similar to this one:

mt76 dma layer is supposed to unmap skb data buffers while keep txwi
mapped on hw dma ring. At the moment mt76 wrongly unmap txwi or does
not unmap data fragments in even positions for non-linear skbs. This
issue may result in hw hangs with A-MSDU if the system relies on IOMMU
or SWIOTLB. Fix this behaviour properly unmapping data fragments on
non-linear skbs.

On same device (e.g. U7612E-H1) PCIE_ASPM causes continuous mcu hangs and
instability. Since mt76x2 series does not manage PCIE PS states, first we
try to disable ASPM using pci_disable_link_state. If it fails, we will
disable PCIE PS configuring PCI registers.
