net: wireless: bcmdhd: Set dpc rt thread priority to max
Dhd dpc rt thread is getting starved on CPU load scenarios.
NIC driver has to get the data in real time, So we need to
set dpc rt thread priority to max. RT thread with SCHED_FIFO
schedule policy priorities are in ascending order
(i.e. 1 is lowest priority, 99 is highest).
So setting the dhd_dpc_thread priority to 99 to avoid starvation.
- Set CUSTOM_DPC_PRIO_SETTING to 99
