The driver maintains elapsed times by repeatedly accumulating the time
since the previous update in a loop. For the elapsed showtime time, the
time difference is truncated to seconds before adding it, leading to a
sizable error over time.
Move the truncation to before calculation of the time difference in
order to remove this error. Also maintain the total elapsed time in the
same way in full seconds, to prevent the unsigned 32-bit counter from
wrapping around after about 50 days.
Testing on a VR9 device shows that the reported line uptime now matches
the actual elapsed wall time. The ADSL variant is only compile-tested,
but it should also work as the relevant code is identical.

(cherry picked from commit db4bf4b968)
Upstream commit e4b92b108c6cd6 ("timekeeping: remove obsolete time
accessors") removed do_gettimeofday(). In Linux 4.19 this was only a
wrapper around ktime_get_real_ts64(). Use ktime_get_real_ts64() now that
the wrapper is gone to fix compilation against Linux 5.4.
Move the ifxmips_mei_interface header to the include directory, it can't
be found otherwise during compilation. The reason for the changed
behaviour is not yet clear, however having header files in an include
directory is more straight forward.
To use the of_device_id struct, the mod_devicetable header need to be
included. Instead of including this header, include the of_platform
header, which includes the mod_devicetable on its own.

Do not leak the user space CFLAGS into the kernel space any more, this
allows us to activate the MIPS16 build.
