[PATCH v1] um: Don't use console_drivers directly

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

console_drivers is kind of (semi-)private variable to the console code.
Direct use of it make us stuck with it being exported here and there.
Reduce use of console_drivers by replacing it with for_each_console().
