octeontx2-af: Workarounds for HW errata
Errata 35038
Software sets NIX_AF_RX_SW_SYNC[ENA] to sync (flush) in-flight packets
the RX data path before configuration changes (e.g. disabling one or
more RQs). Hardware clears [ENA] to indicate sync is done
An issue exists whereby NIX may clear NIX_AF_RX_SW_SYNC [ENA] too
early.
Errata 35057
NIX may corrupt internal state when conditional clocks turn off.
So turnon all clocks by default.
Errata 35786
Parse nibble enable NPC configuration for KEY generation has to be
identical for both Rx and Tx interfaces.
Also corrected endianness configuration for NIX i.e NIX_AF_CFG[AF_BE]
is bit8 and not bit1.
