On my renesas salavator-X, I saw some cavium driver failing crypto
self-tests.
But salvator does not have such hardware.
This is due to cavium/zip driver registering algorithms even if hardware
is not present.
The solution is to move algorithm registration in the probe function.
This permits also to simplify module init/exit by using
module_pci_driver.

This driver is for an FPGA logic core, so there can be arbitrarily many
instances of the bus on a given system. Previously all of the I2C bus
names were "xiic-i2c" which caused issues with lm_sensors when trying to
map human-readable names to sensor inputs because it could not properly
distinguish the busses, for example. Append the platform device name to
the I2C bus name so it is unique between different instances.

Another pass at removing unnecessary use of 'allOf' with a '$ref'.
json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords.

However, the adjtime() call passes in a s64, while the clock adjustment
registers use a s32. When trying to perform adjustments with a large

Examine the incoming delta, and if larger than 1 sec, use the original
(coarse) adjustment method. If smaller than 1 sec, then allow the
FPGA to fold in the changes over a 1 second window.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
Two cleanups to remove an unused filename and typos, and one addition
of an ACPI matching table for a Dell SoundWire SKU without local
microphones.
The main change is the addition of a common 'sof-ssp-amp' machine
driver for devices with amplifiers only (no headset codec) and
different connections using I2S links (Bluetooth offload, HDMI
receiver). It's likely that the amplifier will be swapped out by OEMs,
this machine driver provides a relatively generic solution to avoid
copy-paste of similar solutions.
