video: cfb_console: Allow VGA device to work without i8042 keyboard

So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device
will try to initialize a keyboard device (for x86, it is i8042). But
if i8042 controller initialization fails (eg: there is no keyboard
connected to the PS/2 port), drv_video_init() just simply returns.
This kills the opportunity of using a usb keyboard later with the vga
console, as the vga initialization part is actually ok, only keyboard
part fails. Change the code logic to allow this.
