lcd, amba: remove this driver since it is not used

Since CONFIG_VIDEO_AMBA is not set by any board, it does not seem
to be used, so remove it since there is no way to (compile) test it.

lcd, pxafb: move the pxafb to drivers/video

Since the lcd code was compiled unconditionally for pxa also add CONFIG_PXA_LCD
to the boards using this framebuffer. Since driver/video contains video and
lcd drivers, add lcd to the name to make clear it belongs to common/lcd.c.

common/lcd.c: cleanup use of global variables

console_col, console_row, lcd_line_length, lcd_console_address had
to be declared in board / driver specific code, but were not actually
used there. Get rid of the global variables.
