I can centralize this for SPI, I2C and UART  in Common driver(QUP 
wrapper) but still for QSPI I have to keep this piece of code as is 
because It is not child of QUP wrapper(it doesn't use common code).

I am not sure whether I can move this " Assume peak_bw as twice of 
avg_bw if nothing is mentioned explicitly" to ICC core because the 
factor of 2 is chosen randomly by me.

Regards,

Akash
