[PATCH 22/27] console: Convert pr_print into a single line #define

[Andrey Smirnov <andrew.smirnov@gmail.com>]

If we change dev_printf() to not print device related info at the
start if NULL is passed as device pointer, we can easliy use that
function to do what pr_print does. With this change we can convert
pr_print to be a simple macro that expands into a dev_printf() and
drop a bit of exctra code.
