spi: omap2-mcspi: Add missing suspend and resume calls
I've been wondering still about omap2-mcspi related suspend and resume flakeyness and looks like we're missing calls to spi_master_suspend() and spi_master_resume(). Adding those and using pm_runtime_force_suspend() and pm_runtime_force_resume() makes things work for suspend and resume and allows us to stop using noirq suspend and resume. And while at it, let's use SET_SYSTEM_SLEEP_PM_OPS to simplify things further. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Mark Brown <broonie@kernel.org>
