Delay opening slimbus ports for A2DP for Apache

Delay opening slimbus ports for A2DP for 44.1/88.2k
sample rates if feedback channel is not opened. Else,
delay opening of slimbus port for feedback channel
regardless of A2DP sample rate since feedback channel
is always opened first, then actual A2DP port is opened.
The change is made for Apache.
