89ececd8d1 dptx: Improved sink reordering.
The sink reordering would fail on retrieval of tiling information from a sink
that does not have a Tiled Display Topology (TDT) data block. This behavior is
incorrect since subsequent sinks may be a part of a tiled display.
Modified the function to be void.

7c47ed85dd dptx: Added functions that reorder the sink numbering of the topology.
Added functionality that reorders the sink list such that topologies containing
tiled display(s) will have the contained sinks reordered in a consistent manner.

The need for such functionality exists because not all tiled displays will have
the same internal topologies.
It was observed that two 4k2k MST based monitors (tiled display, 2 sinks) from
different manufacturers would have the left and right images swapped using
identical stream-to-sink mappings.
Thus, the need to obtain the tiled display topology information of all sinks and
their relative tile location is required to send the correct stream to the
desired sink.

52ebe1260c dptx: Improved remote IIC reads/writes to automatically work on 16-byte chunks.
Some monitors don't support sideband messages with IIC reads greater than 16
bytes. This improvement breaks up the higher-level read/write request into
multiple reads/writes that work with up to 16 bytes in size.

These higher-level remote IIC read/write functions also serve as a wrapper for
an IIC read/write in case that the link count total is equal to 1 (a read/write
request to the RX device directly connected to the TX (not "remote")).

d796348e29 dptx: Made the I2C read function more robust.
- Changed the offset from type u8 to u16.
- In order to accomodate offsets greater than 255, a segment pointer is used.
	- The I2C read funciton is now able to access blocks other than the
	block 0 and 1 at a given address. E.g., EDID extension blocks may now be
	accessed by reading from I2C address 0x50 (raw=0xA0/0xA1) and writing
	the appropriate segment pointer and offset.
		- Input offset=0.
			- EDID block 0: I2C read on offset=0 and segptr=0.
		- Input offset=128.
			- EDID block 1: I2C read on offset=128 and segptr=0.
		- Input offset=256.
			- EDID block 2: I2C read on offset=0 and segptr=1.
		- Input offset=384.
			- EDID block 3: I2C read on offset=128 and segptr=1.
		- etc.
	- Writing to the I2C address 0x30 (raw=0x60/0x61) sets the segment
	pointer.
	- Writing to an I2C address sets the offset that will be read from that
	address. E.g., a read of the EDID, starting at offset 128 would be done
	by writing 128 to 0x50, then reading from 0x50.
	- Offsets that cross a 256-byte boundary requiring increment of the
	segment pointer is also handled. E.g. A 16 byte read on input offset 500
	results in the the returned 16 byte array having the first 11 bytes from
	segptr=1 (bytes 244-255) and the last 5 bytes from segptr=2 (bytes 0-4).
