Vladimir 'phcoder' Serbinenko 93c06ff9c6 VGA text support in qemu-mips
* grub-core/Makefile.core.def (kernel): Add term/i386/pc/vga_text.c,
	term/i386/vga_common.c and kern/vga_init.c on qemu-mips.
	* grub-core/kern/mips/qemu_mips/init.c (grub_machine_init): Init vga
	text.
	* grub-core/kern/i386/qemu/init.c: Renamed to ...
	* grub-core/kern/vga_init.c: ... this.
	* grub-core/kern/vga_init.c (VGA_ADDR) [__mips__]: Adjust.
	(grub_qemu_init_cirrus) [__mips__]: Skip PCI and adjust the I/O base.
	* grub-core/term/i386/pc/vga_text.c (VGA_TEXT_SCREEN) [__mips__]:
	Adjust.
	* include/grub/vga.h [GRUB_MACHINE_MIPS_QEMU_MIPS]: Declare
	GRUB_MACHINE_PCI_IO_BASE.
