ASoC: apr: Add separate initial boot flag for ADSP and Modem

Browse source 
apr ignores initial PDR_DOWN event from ADSP/Modem during
boot up. ADSP_DOWN event is wrongly sent to audio drivers
during boot up if it gets MODEM_UP event before ADSP_DOWN.

Added separate flags for both ADSP and Modem events to avoid
this issue.
