Subject: [PATCH 1/3] spi: spi-imx: use "controller" variable consistently in spi_imx_probe()

Near the top of the function, spi_imx->controller is set to
controller (and is of course never modified again). The rest of the
function uses a mix of the two expressions.

For consistency, readability and better code generation, drop all the
spi_imx-> indirections.
