Khem Raj acfa0e0dce runqemu: Add new option to disable vga emulation
When using nographic, explicitly disabling vga is needed some cases
since some qemu firmware (OpenFirmware ) defaults to std vga, and
when vga is enabled then it disables output to serial and redirects
that to vga which is by design, hwoever we expect the console output
to go to serial when using nographic, therefore its important to
disable vga with nographic especially on qemu based ppc platforms

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
