e65a9e480e net: qca_spi: Fix race condition in spi transfers
With performance optimization the spi transfer and messages of basic
register operations like qcaspi_read_register moved into the private
driver structure. But they weren't protected against mutual access
(e.g. between driver kthread and ethtool). So dumping the QCA7000
registers via ethtool during network traffic could make spi_sync
hang forever, because the completion in spi_message is overwritten.

So revert the optimization completely.

55b7a770ae net: qualcomm: move qcaspi_tx_cmd to qca_spi.c
The function qcaspi_tx_cmd() is only called from qca_spi.c. So we better
move it there.

ce68349a35 net: qualcomm: qca_7k: clean up header includes
Currently the includes doesn't reflect the dependencies. So
fix this up by removing all unnecessary entries and add the
necessary ones explicit.
