qcacmn: Setting interrupt mode in soc_init

Setting interrupt mode in dp_soc_init as setting it in
dp_soc_attach is resulting in interrupt mode not set on
subsequent wifi down/up. soc_attach is called only in case
of wifi unload/load and not in case of wifi down/up.
Adding interrupt mode setting in soc_init helps in setting
correct interrupt mode in case of wifi down/up.
