Arnd Bergmann 6051e79bbf misc: mic: fix passing the current time
I noticed that the mic driver passes a 'struct timespec64' as part of
a message into an attached device, where it is used to set the current
system time.

This won't actually work if one of the two sides runs a 32-bit kernel and
the other runs a 64-bit kernel, since the structure layout is different
between the two.

I found this while replacing calls to the deprecated do_settimeofday64()
interface with the modern ktime_get_real_ts() variant, but it seems
appropriate to address both at the same time here.

To make sure we have a sane structure, let's define our own structure
using the layout of the 64-bit kernel.
