demux: fix demux look up table preparation

Array streams represents streams on "many" side i.e. input
for MUX and output for DEMUX.
For DEMUX each stream has masks array - 1 mask per output
channel. Each mask shows, from which input channel data
should be taken.

This commit reverts "demux" part of commit:

zephyr: remove infinite recursion on Broadwell

Broadwell support with Zephyr had only been dry-coded, it has never
been tested, and it contains an infinite recursion bug: functions
platform_timer_get() and arch_timer_get_system() call each other
infinitely. Break the recursion formally, until a proper fix is
available.
