In the existing code every soundwire register read and register write
are kinda blocked. Each of these are using a special command id that
generates interrupt after it successfully finishes. This is really
overhead, limiting and not really necessary unless we are doing
something special.

We can simply read/write the fifo that should also give exactly
what we need! This will also allow to read/write registers in
interrupt context, which was not possible with the special
command approach.

With previous approach number of interrupts generated
after enumeration are around 130:
$ cat /proc/interrupts  | grep soundwire
 21: 130 0 0 0 0 0 0 0 GICv3 234 Edge      soundwire

after this patch they are just 3 interrupts
$ cat /proc/interrupts  | grep soundwire
 21: 3 0 0 0 0 0 0 0 GICv3 234 Edge      soundwire

This has significantly not only reduced interrupting CPU during enumeration
but also during streaming!

We sometimes see COMMAND_IGNORED responses during the clock stop
sequence. It turns out we already have information if devices are
present on a link, so we should only prepare those when they
are attached.

In addition, even when COMMAND_IGNORED are received, we should still
proceed with the clock stop. The device will not be prepared but
that's not a problem.

The only case where the clock stop will fail is if the Cadence IP
reports an error (including a timeout), or if the devices throw a
COMMAND_FAILED response.

The existing code makes no sense, we multiply a channel number by
zero (SDW_BLK_GRP_CNT_1), and the result is used to configure the
block packing mode. Sampling grouping and channel packing are two
separate concepts in SoundWire.

In addition, the bandwidth allocation allocates a vertical slice for
each stream, which makes the use of the PER_CHANNEL packing mode
irrelevant.

Let's use the proper definition for block packing mode (PER_PORT).

This change has no functional impact though since the net result is
the same configuration of the DPN_BlockCtrl3 register, when
implemented.

Currently quirks are only allowed for Slave devices. This patch
describes the need for two quirks at the Master level.

a) bus clash
The SoundWire specification allows a Slave device to report a bus clash
with the in-band interrupt mechanism when it detects a conflict while
driving a bitSlot it owns. This can be a symptom of an electrical conflict
or a programming error, and it's vital to detect reliably.

Unfortunately, on some platforms, bus clashes are randomly reported by
Slave devices after a bus reset, with an interrupt status set even before
the bus clash interrupt is enabled. These initial spurious interrupts are
not relevant and should optionally be filtered out, while leaving the
interrupt mechanism enabled to detect 'true' issues.

This patch suggests the addition of a Master level quirk to discard such
interrupts. The quirk should in theory have been added at the Slave level,
but since the problem was detected with different generations of Slave
devices it's hard to point to a specific IP. The problem might also be
board-dependent and hence dealing with a Master quirk is simpler.

b) parity

Additional tests on a new platform with the Maxim 98373 amplifier
showed a rare case where the parity interrupt is also thrown on
startup, at the same time as bus clashes. This issue only seems to
happen infrequently and was only observed during suspend-resume stress
tests while audio is streaming. We could make the problem go away by
adding a Slave-level quirk, but there is no evidence that the issue is
actually a Slave problem: the parity is provided by the Master, which
could also set an invalid parity in corner cases.

HP Spectre x360 Convertible devices expose invalid _ADR fields in the
