[PATCH] PM: make it possible to disable console suspending
Change suspend_console() so that it waits for all consoles to flush the remaining messages and make it possible to switch the console suspending off with the help of a Kconfig option.

44 This option turns off the console suspend mechanism that prevents
45 debug messages from reaching the console during the suspend/resume
46 operations. This may be helpful when debugging device drivers'
47 suspend/resume routines, but may itself lead to problems, for example
48 if netconsole is used.
