tty: Disable default console blanking intervalsubmit/tizen_6.0/20210107.042850submit/tizen_6.0/20210107.014309submit/tizen/20210107.014139accepted/tizen/unified/20210107.123417accepted/tizen/6.0/unified/20210107.080409tizen_6.0accepted/tizen_6.0_unified

Console blanking is not enabling DPMS power saving (thereby negating any
power-saving benefit), and is simply turning the screen content blank. This
means that any crash output is invisible which is unhelpful on a server
(virtual or otherwise).
Furthermore, CRT burn in concerns should no longer govern the default case.
Affected users could always set consoleblank on the kernel command line.
