Currently, the pmc_mux/conn driver uses integer fields to store the
USB-2 and USB-3 port numbers from the SoC's point of view. Specifying
these as integers in the devicetree is error-prone, and this
information can instead be represented using pointers to the USB-2 and
USB-3 devices. The port numbers can then be obtained from the paths of
the linked devices, i.e. dev->path.usb.port_id.
Modify the driver to store device pointers instead of integer port
numbers, and update all devicetrees using the driver. These are the

number. For example, if TCSS port 1 and 3 are enabled on the board,
coreboot will interpret port numbers as 0 and 2, but since only 2 ports
are enabled in the system EC will assign port numbers as 0 and 1.
This creates a port number mismatch while communicating between EC and

The current implementations of edid_read() and segments_edid_read() have
a few problems:
1. The type of variable `c` is incorrect, not matching the return type
of sp_tx_aux_rd(). In addition, the meaning of `c` is unknown.
2. It is pointless to do `cnt++` when sp_tx_aux_rd() fails.
3. These two functions ignore the return value of
anx7625_reg_block_read().
4. In segments_edid_read(), anx7625_reg_write() might return a positive
value on failure.
Fix all of the 4 issues, and modify the code to be closer to kernel
5.10's implementation (drivers/gpu/drm/bridge/analogix/anx7625.c). Note
that, however, unlike in kernel, anx7625_reg_block_read() here doesn't
return the number of bytes. On success, 0 is returned instead.
In addition, following coreboot's convention, always return negative
error codes. In particular, change the return value to -1 for
edid_read() and segments_edid_read() on failure.

In cases where the existing code already accounts for null pointers, it
is better to use `probe_resource` instead, which returns a null pointer
instead of dying.
