In fine timing measurements, the calculation is affected by
2 parts: timing of packets over the air, which is platform
independent, and platform-specific delays, which are dependent
on things like antenna cable length and type.
Add a sysfs file which allows to get/set these platform specific
delays, separated into the TX and RX components.
There are 2 key scenarios where the file can be used:
1. Calibration - start with some initial values (for example,
the default values at startup), make measurements at a known
distance, then iteratively change the values until the
measurement results match the known distance.
2. Adjust the delays when platform starts up, based on known
values.

Can't this go via nl80211? sysfs is not really supposed to be used for
something like this.
