Naveen Mamindlapalli 13c9f4dc10 octeontx2-pf: Fix NIX_AF_TL3_TL2X_LINKX_CFG register configuration

For packets scheduled to RPM and LBK, NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
selects the TL3 or TL2 scheduling level as the one used for link/channel
selection and backpressure. For each scheduling queue at the selected
level: Setting NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG[ENA] = 1 allows
the TL3/TL2 queue to schedule packets to a specified RPM or LBK link
and channel.

There is an issue in the code where NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
is set to TL3 where as the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG is
configured for TL2 queue in some cases. As a result packets will not
transmit on that link/channel. This patch fixes the issue by configuring
the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG register depending on the
NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] value.
