[PATCH next v3 2/3] printk: define CONSOLE_LOG_MAX in printk.h

[John Ogness <john.ogness@linutronix.de>]

CONSOLE_EXT_LOG_MAX for extended console messages is already defined
in printk.h. Define CONSOLE_LOG_MAX there as well so that future
changes can make use of the constant for non-extended console
messages.
