spi: omap2-mcspi: Disable multi mode when CS should be kept asserted after message

Browse source

[ Upstream commit a5bf527229 ]

When the last transfer of a SPI message has the cs_change flag, the CS is kept
asserted after the message.
Multi-mode can't respect this as CS is deasserted by the hardware at the end of
the message.

Disable multi-mode when not applicable to the current message.
