omap2-mcspi multi mode

[Colin Foster <colin.foster@xxxxxxxxxxxxxxxx>]

Hi Louis,

I found that commit e64d3b6fc9a3 ("spi: omap2-mcpsi: Enable MULTI-mode
in more situations") caused a regression in the ocelot_mfd driver. It
essentially causes the boot to hang during probe of the SPI device.

The following patch restores functionality. I can hook up a logic
analyzer tomorrow to get some more info, but I wanted to see if you had
any ideas.

        err = spi_setup(spi);
        if (err)
