lcd-common: Remove direct style (line decorations) from lcd-puts* functions.

Browse source 
This logic is moved into apps (put_line()) which can better handle line
decorations with respect to scrolling, mulitline and other complications.

Firmware doesn't need this. The remaining drawing function know only one style,
that is foreground on background/backdrop (changing drawmode is still supported).
