Subject: LCD: Add an option to skip registration as an stdio output

This patch adds an option to skip the registration of LCD stdio output for
boards that want to show different text on LCD than on serial output (or
the active stdout selected by the environment variable).

Subject: video: ipu: fix out of bounds access

We need to access reg stp_rep9, but not stp_rep[(9 - 1) / 2].
If using "__raw_writel(0, DI_STP_REP(disp, 9))", this will exceeds
the size of stp_rep array.
