Host memory required for firmware is allocated while handling wmi service ready event. Right now, wmi service ready is handled in tasklet context and it calls dma_alloc_coherent() with atomic flag (GFP_ATOMIC) to allocate memory in host needed for firmware. The problem is, dma_alloc_coherent() with GFP_ATOMIC fails in the platform (at least in AP platform) where it has less atomic pool memory (< 2mb). QCA99X0 requires around 2 MB of host memory for one card, having additional QCA99X0 card in the same platform will require similarly amount of memory. So, it's not guaranteed that all the platform will have enough atomic memory pool. Fix this issue, by handling wmi service ready event in workqueue context and calling dma_alloc_coherent() with GFP_KERNEL. mac80211 work queue will not be ready at the time of handling wmi service ready. So, it can't be used to handle wmi service ready. Also, register work gets scheduled during insmod in existing ath10k_wq and waits for wmi service ready to completed. Both workqueue can't be used for this purpose. New auxiliary workqueue is added to handle wmi service ready.
