Kevin Hilman e83df17f17 OMAP2+: PM/serial: fix console semaphore acquire during suspend 
commit 0d8e2d0dad (OMAP2+: PM/serial:
hold console semaphore while OMAP UARTs are disabled) added use of the
console semaphore to protect UARTs from being accessed after disabled
during idle, but this causes problems in suspend.

During suspend, the console semaphore is acquired by the console
suspend method (console_suspend()) so the try_acquire_console_sem()
will always fail and suspend will be aborted.

To fix, introduce a check so the console semaphore is only attempted
during idle, and not during suspend.  Also use the same check so that
the console semaphore is not prematurely released during resume.

Thanks to Paul Walmsley for suggesting adding the same check during
resume.
