Subject: [PATCH] Add possibility to set /dev/tty number

Hello,

In Linux there is no way to set the number of tty devices or console
to create. By default the kernel create 64 /dev/tty devices. what is
too much for embedded system with limited resources. As all these 64
devices are not necessary or mandatory for the kernel proper working,
I add a config option to set the desired tty. The lowest number you
can set is 1 and the highest is 63, any value respectively below or
above that, will cause a kconfig invalid entry pop-up.

Please keep me update.

Best Regards
