[PATCH v2 2/3] spi: spi-fsl-lpspi: Move controller initialization further down

[Alexander Stein <alexander.stein@xxxxxxxxxxxxxxx>]

This is a preparation for reading number of chip-selects from hardware.
This needs IO resources mapped and peripheral clocking enabled.
No functional changes intended.
