This code accidentally uses the RX macro twice instead of the RX and TX.

If alloc_mem() fails in mcs_register_interrupts(), it should return error
code.

Hardware triggers an interrupt for events like PN wrap to zero,
PN crosses set threshold. This interrupt is received
by the MCS_AF. MCS AF then finds the PF/VF to which SA is mapped
and notifies them using mcs_intr_notify mbox message.
PF/VF using mcs_intr_cfg mbox can configure the list
of interrupts for which they want to receive the
notification from AF.

Add mailbox messages to return the resource stats to the
caller. Stats of SecY, SC and SAs as per the macsec standard,
TCAM flow id hits/miss, mailbox to clear the stats are
implemented.

Out of all the TCAM entries, reserve last TX and RX TCAM flow
entry(low priority) so that normal traffic can be sent out and
received. The traffic which needs macsec processing hits the
high priority TCAM flows. Also install a FLR handler to free
the allocated resources for PF/VF.

To establish a macsec connection association netdev driver
needs hardware resources like SecY, TCAM flows, SCs and SAs.
This patch manages allocating, freeing and configuring those
resources. AF consumers can request resources and configure them
via these mailbox messages. AF can allocate until it runs out of
hardware resources.

There are set of configurations to be done at MCS port level like
bringing port out of reset, making port as operational or bypass.
This patch adds all the port related mailbox message handlers
so that AF consumers can use them.

CN10K-B and CNF10K-B has macsec block(MCS) to encrypt and
decrypt packets at MAC level. This block is a global resource
with hardware resources like SecYs, SCs and SAs and is in
between NIX block and RPM LMAC. CN10K-B silicon has only one MCS
block which receives packets from all LMACS whereas CNF10K-B has
seven MCS blocks for seven LMACs. Both MCS blocks are
similar in operation except for few register offsets and some
configurations require writing to different registers. Those
differences between IPs are handled using separate ops.
This patch adds basic driver and does the initial hardware
calibration and parser configuration.
