soc: swr-mstr: Fix random headset detection issue on scuba

Browse Source 
When headset is inserted and reboot device sometimes
headset is not detected after reboot as host_irq from
swr slave gets masked. This is because of cmd error seen
after clearing all irq which results in fifo flush.
Read swrslave irq before clearing so as to resolve cmd error.
Also enable host irq after clearing enum interrupt at master.
This ensures irq is properly enabled.
