Increase the size of temporary print buffer on stack to fix the
following warnings reported by LKP.
Since all the input parameters of snprintf() are under control
of this driver, it is not possible to trigger and overflow here,
but since the print buffer is on stack and discarded once driver
probe() finishes, it is not an issue to increase it by 10 bytes
and fix the warning in the process. Make it so.

The device_get_match_data(), is to get match data for firmware interfaces
such as just OF/ACPI. This driver has I2C matching table as well. Use
i2c_get_match_data() to get match data for I2C, ACPI and DT-based
matching.

Rework the write operation such that the Byte Count register is written with
a single raw i2c write outside of regmap using transfer which does specify
the number of bytes to be transfered, one in this case, and which makes the
expected subsequent write transfer look like address+register+data, and then
make use of this method. Without this change, the Byte Count register write
in probe() would succeed as it would provide the byte count as part of its
write payload, but any subsequent writes would fail due to this Byte Count
register programming. Such failing writes happens e.g. during resume, when
restoring the regmap content.

In order to reload registers into the clock generator on resume using
regcache_sync(), it is necessary to select one of the regcache types
which are not NONE. Since this device has some 7 registers, use the
simplest one, FLAT. The regcache code complains about REGCACHE_NONE
being selected and generates a WARNING, this fixes that warning.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter")
convert back to (the new) .probe() to be able to eventually drop
.probe_new() from struct i2c_driver.

Add driver for the Skyworks Si521xx PCIe clock generators. Supported models
are Si52144/Si52146/Si52147, tested model is Si52144. It should be possible
to add Si5213x series as well.
