Docs: printk: add 'console=null|""' to admin/kernel-parameters
Tell about 'console=null|""' and how to use it.
It can be helpful to set (enable) CONFIG_NULL_TTY so that the ttynull
driver is available. This avoids problems with stdin/stdout/stderr of
the init process. Howevere, CONFIG_NULL_TTY cannot be enabled by default
because it can be used by mistake, see the commit a91bd6223ecd ("Revert
"init/console: Use ttynull as a fallback when there is no console"").
