Subject: [PATCH net-next v1 0/2] add delay abstraction (sleep functions)

Add an abstraction for sleep functions in `include/linux/delay.h` for
dealing with hardware delays. `delay.h` supports sleep and delay (busy
wait). This adds support for sleep functions used by QT2025 PHY driver
to sleep until a PHY becomes ready.

The old rust branch has the delay abstraction which supports msleep()
with a helper function which rounds a `Duration` up to the nearest
milliseconds.

This adds fsleep() support instead of msleep(). fsleep() can handle
various lengths of delay by internally calling an appropriate sleep
function including msleep().
