Log:
loader: vidc_init should also erase the screen
Inject \e[J to erase the initial loader screen. We have two options,
find where out cursor is and use BIOS scroll for data from boot2 or erase the
display and start from origin. Erasing the screen is easier and we also
get the screen buffer initialized.
