User pd needs additional interrupts like spawn. Instead of going with qcom_q6v5_init(), we defined a new function to register userpd rproc interrupts in mpd driver. Since userpd rproc uses some of common interrupts like fatal, ready, static is removed from ISR handler and used in userpd interrupt registration.
