Function 'bypass_pipe_rst' and 'set_phy_for_ssc' can be
written in a cleaner way. Instead of use comments to see which
bits are the ones which are being enabled add new macros with
that information using BIT and GENMASK kernel macros. Avoid the
use of set_pcie_phy which is kind of dark and use new macros also
resetting and adding bits using bitwise operators directly in the
code. Now these function are offset-based on the port to use them
cleaner in driver probe functio and improving readability.

When the BCM2835 audio output is used, userspace sees a jitter up to 10ms
in the audio position, aka "delay" -- the number of frames that must
be output before a new frame would be played.
Make this a bit nicer for userspace by interpolating the position
using the CPU clock.
The overhead is small -- an extra ktime_get() every time a GPU message
is sent -- and another call and a few calculations whenever the delay
is sought from userland.
At 48,000 frames per second, i.e. approximately 20 microseconds per
frame, it would take a clock inaccuracy of
20 microseconds in 10 milliseconds -- 2,000 parts per million --
to result in an inaccurate estimate, whereas
crystal- or resonator-based clocks typically have an
inaccuracy of 10s to 100s of parts per million.
