The MAX98363 smart speaker amp can be connected over SoundWire and be
configured for mainboards to use:
- Data Port 0 and Bulk Register Access is not supported
- Data Port 1 is the 32bit data input for the speaker path
The data port and audio mode properties are filled out as best as
possible with the datasheet as a reference.
The ACPI address for the codec is calculated with the information in
the codec driver combined with the devicetree.cb hierarchy where the
link and unique IDs are extracted from the device path.
For example this device is connected to master link ID 2 and has strap
settings configuring it for unique ID 0.
chip drivers/soundwire/max98363
register "desc" = ""Left Speaker Amp""
device generic 2.0 on end
end
This driver was tested with the rex0 reference design by booting
and disassembling the runtime SSDT to ensure that the devices have the
expected address and properties.

cb_err_t was meant to be used in place of `enum cb_err` in all
situations, but the choice to use a typedef here seems to be
controversial. We should not be arbitrarily using two different
identifiers for the same thing across the codebase, so since there are
no use cases for serializing enum cb_err at the moment (which would be
the primary reason to typedef a fixed-width integer instead), remove
cb_err_t again for now.

Our MIPI panel initialization framework differentiates between DCS and
GENERIC commands, but the exact interpretation of those terms is left to
the platform drivers. In practice, the MIPI DSI transaction codes for
these are standardized and platforms always need to do the same
operation of combining the command length and transfer type into a
correct DSI protocol code. This patch factors out the various
platform-specific DSI protocol definitions into a single global one and
moves the transaction type calculation into the common panel framework.
The Qualcomm SC7180 implementation which previously only supported DCS
commands is enhanced to (hopefully? untested for now...) also support
GENERIC commands. While we're rewriting that whole section also fix some
other issues about how exactly long and short commands need to be passed
to that hardware which we identified in the meantime.

It doesn't make sense to store the orientation field directly in the
panel information structure, which is supposed to be reuseable between
different boards. The thing that determines orientation is how that
panel is built into the board in question, which only the board itself
can know. The same portrait panel could be rotated left to be used as
landscape in one board and rotated right to be used as landscape in
another. This patch moves the orientation field out of the panel
structure back into the mainboards to reflect this.

Sounds like we prefer to have this under drivers/ instead of device/.
Also move all MIPI-related headers out from device/ into their own
directory.
