mwl8k: interrupt handling changes
We do not need to enable all the interrupts in mwl8k_probe_hw. We need to enable only MWL8K_A2H_INT_OPC_DONE interrupt for sending commands to the firmware. Keep the other interrupts masked in mwl8k_probe_hw. Also, in mwl8k_start, where we expect other interrupts, enable only those interrupts we are interested in.
