Do not free skb inside that function
Preparation for further cleanup

In the implementation of __mt76x02u_mcu_send_msg() the skb is consumed
all execution paths except one. Release skb before returning if
test_bit() fails.

Introduce headroom and tailroom to mt76_mcu_ops data structure in order
to unify the routine used for mcu message allocation. This is a
preliminary patch to add mt7663u support

Introduce mt76_mcu data structure to contain common fields between
mt76u_mcu and mt76e_mcu.
Initialize mcu common fields in mt76_alloc_device().
Rely on mt76_mcu in mt76_mcu_rx_event and in mt76_mcu_get_response
in order to reuse them in usb code

Use usb_bulk_msg for reading MCU command responses. This simplify code
a lot.
Together with 97a3005759c ("mt76usb: allow mt76u_bulk_msg be used
for reads") it also fix possible problems with rx data buffers
not being aligned and contained within single page. After doing
page_frag_alloc(1024) consecutive page_frag_alloc(PAGE_SIZE) will
alloc PAGE_SIZE buffer at PAGE_SIZE - 1024 offset.

Do not use scatter-gather buffers for mcu commands.

We don't need to send firmware data asynchronously, much simpler is just
use synchronous usb_bulk_msg().

Move mt76_mcu_msg_alloc in mt76-core module and remove duplicated code.

We almost always use patter like this:
skb = mt76_mcu_msg_alloc(dev, &msg, sizeof(msg));
return mt76_mcu_send_msg(dev, skb, CMD_FUN_SET_OP, wait_resp);
This is not needed, we can allocate skb in mcu_send_msg routine.

Move mt76u_skb_dma_info routine in mt76x02-usb module and rename it in
mt76x02u_skb_dma_info. Moreover move mt76x02u_set_txinfo in
mt76x02_usb_core.c. This is a preliminary patch to move MT_TXD_INFO,
MT_MCU_MSG and MT_RX_FCE_INFO defs in mt76x02-lib module since other
chipsets (e.g. mt7603) use different dma definitions
