3a23a15f09 dptx: Optimize read/write GUID functions to use new remote reads/writes.
The remote read/write functions serve as a wrapper in case the target RX device
is directly connected to the TX (link count total is equal to 1).
These functions may be called instead of the read/write GUID functions doing the
same thing.

518eb68d03 dptx: Improved remote DPCD reads/writes to automatically work on 16-byte chunks.
Some monitors don't support sideband messages with AUX 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 DPCD read/write functions also serve as a wrapper for
an AUX 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).

2d318f6d74 dptx: Broadcast messages need to have an LCR of 6.
An LCR (link count remaining) value of 6 is used to protect against loops.
If the LCR isn't processed at each node and attempted to be broadcasted on all
ports, waiting for a reply, a loop in the topology will result in the broadcast
message being forwarded infinitely.
Because of this, an LCR of 0 will prevent the message from being forwarded to
subsequent DP nodes.
