302075f85e29d6e658aeec75f50a90eec23f3726 hw/display/vga: Do not reset 'big_endian_fb' in vga_common_reset()
The 'pci-vga' device allow setting a 'big-endian-framebuffer'
property since commit 3c2784fc864 ("vga: Expose framebuffer
byteorder as a QOM property"). Similarly, the 'virtio-vga'
device since commit 8be61ce2ce3 ("virtio-vga: implement
big-endian-framebuffer property").
Both call vga_common_reset() in their reset handler, respectively
pci_secondary_vga_reset() and virtio_vga_base_reset_hold(), which
reset 'big_endian_fb', overwritting the property. This is not
correct: the hardware is expected to keep its configured
endianness during resets.
Move 'big_endian_fb' assignment from vga_common_reset() to
vga_common_init() which is called once when the common VGA state
is initialized.
