spi: imx: support word delay in ecspi 
Merge series from Jonas Rebmann <jre@pengutronix.de>:

The i.MX SPI controller supports inserting a configurable delay between
subsequent words, which is needed for some slower devices that couldn't
keep up otherwise.

This patch series introduces support for the word delay parameters for
i.MX51 onwards.

The SPI clock (CSRC=0) was chosen as the clock source over the also
available 32.768 KHz Low-Frequency Reference Clock (CSRC=1). The sample
period control bits (SAMPLE_PERIOD) are set to the selected word delay
converted to SPI clock cycles. A deviation from the requested number of
wait cycles and the actual word delay was observed via both software
timings and oscilloscope measurements and accounted for.

The Chip Select Delay Control bits in the Sample Period Control Register
remain zero.

Behaviour on i.MX35 and earlier, where the CSPI interface is used,
remains unchanged.
