iio: max31856: add option for setting mains filter rejection frequency
This sensor has an embedded notch filter for reducing interferences caused
by the power mains. This filter can be tuned to reject either 50Hz or 60Hz
(and harmonics).
Currently the said setting is left alone (the sensor defaults to 60Hz).
This patch introduces a IIO attribute that allows the user to set the said
filter to the desired frequency.
NOTE: this has been intentionally not tied to any DT property to allow
the configuration of this setting from userspace, e.g. with a GUI or by
reading a configuration file, or maybe reading a GPIO tied to a physical
switch or accessing some device that can autodetect the line frequency.

"Here is a mix of a number of IIO driver fixes for 5.4-rc7, and a whole
new staging driver.
The IIO fixes resolve some reported issues, all are tiny.
The staging driver addition is the vboxsf filesystem, which is the
VirtualBox guest shared folder code. Hans has been trying to get
filesystem reviewers to review the code for many months now, and
Christoph finally said to just merge it in staging now as it is
stand-alone and the filesystem people can review it easier over time
that way.
I know it's late for this big of an addition, but it is stand-alone.
The code has been in linux-next for a while, long enough to pick up a
few tiny fixes for it already so people are looking at it.
