The SPI IP core in the Marvell Armada 3700 is similar to the one in the
other Armada SoCs. But the differences are big enough that it makes
sense to introduce a new driver instead of cluttering the old

v3:
- Really use hz now in equation
- Add comment that the DT property for the input clock is deprecated
and the clock infrastructure should be used, once available for
mvebu in U-Boot
v2:
- Evaluated hz and used values provided by the DT in mvebu_spi_set_speed()
as suggested by Jagan
