When the upstream device issues an ALLOCATE_PAYLOAD sideband message request,
this table is updated to represent the allocated bandwidth for each stream.

The "I2C map" terminology is used to refer to a set of I2C entries for a given
port. Each I2C entry contains an I2C address associated with that entry,
alongside a user-defined data structure which is to be pointed to.
This is the mechanism for which the driver allows the RX application to control
what data to be sent for a given I2C address when a REMOTE_I2C_READ is issued
by an upstream device.

Topology contains information for responding to LINK_ADDRESS sideband messages
and I2C maps for each port for responding to REMOTE_I2C_READ.

- ReplyType: The driver already checks for NACK elsewhere.
- RequestId: The link address reply will always carry the LINK_ADDRESS tag.

Both RX and TX cases use the CRC functions so having *Tx* in the function name
is incorrect.

Larger messages will need to be split into multiple fragments.
- The MsgData member carries all information.
- The FragmentNum member indicates the last fragment processed.
- The header reflects the latest fragment.

The IP documentation "recommends" enabling the following:
- Issuing reset at every training iteration.
- Issuing reset at every link rate change.
- Issuing reset at start of training pattern 1.

No need for this since the handler will never be called if the interrupts are
masked in the first place.
Also, by default, nested interrupts are disabled and it is up to the user to
explicitly request nested interrupts - allow this.
The interrupt mask should already apply in hardware.

Even if link training succeeds, sometimes, the link will fall if the link is
enabled prior to the training pattern being turned off.

AUX reply now makes use of the REPLY_STATUS register rather than
INTERRUPT_STATUS. It seems that INTERRUPT_STATUS may be updated before
REPLY_STATUS gets updated, resulting in a race condition.
