In some scenario before enabling the WDI pipe setup QUOTA monitor
command sending to uC which leading to NULL pointer access.
So adding changes to setup uC event from connect wdi API and sending
set QUOTA monitor and BW monitor commands to if uC setup event
ring completed.

some time read the SCRATCH register again and also printing the
test bus registers and Q6 channel state in failed scenario.

In suspend scenario while checking channel empty scenario
updating the event ring RP pointer from direct register, it
may cause mismatch in reading in polling context. To avoid
discrepancy reading RP pointer DDR location.

Use read memory barrier before reading event from event ring.
Since ring is shared resource between IPA h/w and IPA driver
dma_rmb is used to ensure memory write is complete before
reading from driver.

We observe the IPA RX stall due to the DEAGGR_ERR_IRQ
of PACKET_SIZE > FRAME_SIZE on WAN PROD pipe.
In IPA, some of de-aggregation error handling checks
are dependent on the syspipe_err_detection config bit.
Adding IGNORE_MIN_PKT_ERR bit for WAN PROD as well based
on recommendations.
