There is a mass of jobs between spin lock and unlock in the hardware
IRQ which will occupy much time originally. To make system work more
efficiently, this patch moves the jobs to the soft IRQ (bottom half) to
reduce the time in hardware IRQ.

Since each skb in RX ring is reused instead of new allocation, we can
treat the DMA in a more efficient way by DMA synchronization.

Sorry, also forget to place the version differ
wasted memory, this patch follows David's
suggestion [1] and uses general buffer arrays, instead of skbs as the
elements in RX ring.

According to the vendor driver, the HCI_QUIRK_RESET_ON_CLOSE flag is set
during probing. So, this patch makes Realtek's BT reset on close to fix
this issue.

route become confused. So, the output volume cannot be changed by

2. Misses the headset mic pin node.
This patch disables the confusing speaker (NID 0x14) and enables the
headset mic (NID 0x19).
