The SPI stack relies on a proper bus speed/mode configuration
by calling dm_spi_claim_bus(). However the hitherto code
allowed to accidentally override those settings in
the spi_get_bus_and_cs() routine.
The initially established speed could be discarded by using
the slave platdata, which turned out to be an issue on
the platforms whose slave maximum supported frequency
is not on par with the maximum frequency of the bus controller.
This patch fixes above issue by configuring the bus from
spi_get_bus_and_cs() only in case it was not done before.

This is a port of the kernel's spi-nxp-fspi driver. It uses the new
spi-mem interface and does not expose the more generic spi-xfer
interface. The source was taken from the v5.3-rc3 tag.
The port was straightforward:
- remove the interrupt handling and the completion by busy polling the
controller
- remove locks
- move the setup of the memory windows into claim_bus()
- move the setup of the speed into set_speed()
- port the device tree bindings from the original fspi_probe() to
ofdata_to_platdata()
There were only some style change fixes, no change in any logic. For
example, there are busy loops where the return code is not handled
correctly, eg. only prints a warning with WARN_ON(). This port
intentionally left most functions unchanged to ease future bugfixes.
This was tested on a custom LS1028A board. Because the LS1028A doesn't
have proper clock framework support, changing the clock speed was not
tested. This also means that it is not possible to change the SPI
speed on LS1028A for now (neither is it possible in the linux driver).

At present the driver can end up with timing parameters which are slightly
faster than those expected. It is possible to optimise the parameters to
get the best possible result.
Create a new function to handle the timing calculation. This uses a table
of defaults for each speed mode rather than writing it in code.
The function works by calculating the 'period' of each bit on the bus in
terms of the input clock to the controller (IC_CLK). It makes sure that
the constraints are met and that the different components of that period
add up correctly.
This code was taken from coreboot which has ended up with this same
driver, but now in a much-different form.

At present the driver uses an approximation for the bus clock, e.g. 166MHz
instead of 166 2/3 MHz.
This can result in small errors in the resulting I2C speed, perhaps 0.5%
or so.
Adjust the existing code to start from the accurate figure, even if later
rounding reduces this accuracy.
Update the bus speed code to work in KHz instead of MHz, which removes
most of the error.

mtk_clk_find_parent_rate is calling clk_get_rate to know the rate
of a parent clock. clk_get_rate returns a ulong, while
mtk_clk_find_parent_rate returns an int. This implicit cast creates
an issue for clock rates big enough to need the full 32 bits to
store its data. When that happen the clk rate will become incorrect
because of the implicit cast between ulong -> int -> ulong.
