spi: omap2-mcspi: Remove unnecessary pm_runtime_force_suspend()
Commit 5a686b2c9ed4 ("spi: omap2-mcspi: Idle hardware during suspend
and resume") added calls for pm_runtime_force_suspend() and
pm_runtime_force_resume() to make sure spi is idled between
device_prepare() and device_complete().
But testing Linux next, I now noticed that we will get the following:
spi_master spi0: Failed to power device: -13
Looking at things more turns out we can just remove this non-standard
code. I was probably testing with some extra experimental patches
earlier when I thought we need pm_runtime_force_suspend() and
pm_runtime_force_resume().
Fixes: 5a686b2c9ed4 ("spi: omap2-mcspi: Idle hardware during suspend
and resume")
