spi: fsl-dspi: clean up after failed suspend and resume

Browse source

dspi_suspend() disabled the IRQ before spi_controller_suspend(),
but ignored a suspend failure and kept tearing the device down.
Restore the IRQ and return the error if suspend fails.

dspi_resume() also left the clock prepared if controller resume or
hardware init failed. Route those failures through clock cleanup.
