The struct spi_message can be embedded into another structures.
With that the flexible array might be problematic as sparse
complains about it, although there is no real issue in the code
because when the message is embedded it doesn't use flexible array
member. That memeber is a private to spi_message_alloc() API, so
move it to that API in a form of an inherited data type.

The CSI IP found inside the Renesas RZ/V2M SoC supports
both SPI host and SPI target roles.

When working in target mode, the CSI IP has the option
of using its Slave Selection (SS) pin to enable TX and RX
operations. Since the SPI target cannot control the clock,
when working as target it's best not to stop operations
during a transfer, as by doing so the IP will not send or
receive data, regardless of clock and active level on pin SS.
A side effect from not stopping operations is that the RX
FIFO needs to be flushed, word by word, when RX data needs
to be discarded.

Finally, when in target mode timings are tighter, as missing a
deadline translates to errors being thrown, resulting in
aborting the transfer. In order to speed things up, we can
avoid waiting for the TX FIFO to be empty, we can just wait
for the RX FIFO to contain at least the number of words that
we expect.

Add target support to the currently existing CSI driver.

The CSI IP found inside the Renesas RZ/V2M SoC can also work
in SPI target mode.
When working in target mode, the IP will make use of the SS
(Slave Selection) pin, with "low" as default active level.
The active level of SS can be changed to "high" upon setting
property "spi-cs-high" to true.
By default, the SS will be used in target mode, unless property
"renesas,csi-no-ss" is set to true, in which case data will be
shifted in and out purely based on clock activity, and the
logic level of the SS pin will be completely ignored.

When the SPI QUP controller is used together with a DMA engine it needs
to vote for the interconnect path to the DRAM. Otherwise it may be
unable to access the memory quickly enough.

The requested peak bandwidth is dependent on the SPI core/bus clock so
that the bandwidth scales together with the selected SPI speed.

To avoid sending votes too often the bandwidth is always requested when
a DMA transfer starts, but dropped only on runtime suspend. Runtime
suspend should only happen if no transfer is active. After resumption we
can defer the next vote until the first DMA transfer actually happens.

Commit 7ef9651e ("clk: Provide new devm_clk helpers for prepared
and enabled clocks") provides a new helper function for prepared and
enabled clocks when a driver keeps a clock prepared (or enabled) during
the whole lifetime of the driver. So where drivers get clocks and enable
them immediately, it can be combined into a single function
devm_clk_get_*(). Moreover, the unprepare and disable function
has been registered to devm_clk_state, and before devm_clk_state is
released, the clocks will be unprepareed and disable, so it is unnecessary
to unprepare and disable clocks explicitly when remove drivers or in the
error handling path.
