dm: video: support more escape sequences

The EFI subsystems needs to know the size of the terminal. If the
environment variable

stdout = serial,vidconsole

this size cannot be read from the video console. So the EFI subsystem
sends escape sequences to read the size. With this patch we get support
for the following escape sequences:

ESC "7" Save cursor position
ESC "8" Restore cursor position
