SSP can either be in paused or prepared state during stream pause
depending on the state of the other SSP data direction. Make sure this
is taken into account.

This patch decouples the first and second stage in two phase conversion
that is used for out/in rate fractions with high numerator or denominator
value. For e.g. 44.1 -> 48 kHz 160/147 fraction the 1st 8/7 stage and
2nd 20/21 stage are executed number of times close to period length in
time used for the scheduling rate. The number of consumed and produced
samples per copy() is no more constant. The latency of 44.1 kHz is
decreased about 2 ms and processing load is less variable.
This patch removes mute feature due to non-compatibility with variable
length data processing. It can be introduced later if needed as different
implementation.
The polyphase filter is also optimized slightly. More optimizations will
follow.

Current timer has been upgraded to 64-bit but work queue utility
still uses 32-bit.
So timer->hitime can't be added rightly because the 64-bit time
is truncated by work queue utility.
"rmbox" will still receive 32-bit timestamp value only and can't
be upgraded to 64-bit timestamp.

Before the 1st rollover, timer->hitimeout = 0, it will cause
platform_timer_64_handler() set timeout = 1.
So the time irq is forced to be fired at the beginning of rollover.
And the timeout of platform_timer_set() will be invalid and work
queue cannot be fired.
Just set the new hitimeout to timer->hitimeout.
timer->hitime will be added in the next rollover.
It is unnecessary to check timer->hitimout > 0.
