We use skb_desc->tx_rate_flags from entry as rate[].flags even if
skb does not match status. Patch corrects flags and also fixes
mcs for legacy rates.

rt2800_rate_from_status() is based on Felix's mt76
mt76x2_mac_process_tx_rate() function.

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 Generic PHY driver is a catch-all PHY driver and it should preserve
whatever prior initialization has been done by boot loader or firmware
agents. For specific PHY device configuration it is expected that a
specialized PHY driver would take over that role.

Resetting the generic PHY was a bad idea that has lead to several
complaints and downstream workarounds e.g: in OpenWrt/LEDE so restore
the behavior prior to 87aa9f9c ("net: phy: consolidate PHY
