Add a new driver bochsfb, which is a framebuffer device emulated by QEMU, and bochs.
Tested with QEMU devices:
-vga std
-vga virtio
-device VGA
-device bochs-display
-device secondary-vga
-device virtio-vga
This driver is useful when kern is booted without firmware runtime video support. (i.e. fdt booting for riscv/arm, PMON/YAMON for MIPS). For x86, genfb is more sutiable, thus only enabled for arm generic kernel at the moment.
