Thomas Zimmermann 7d09c76063 drm/mgag200: Don't read-back PCI option register before writing
Remove the read operation from mgag200_init_pci_options(). It was
incorrectly added while refactoring the code. Reading the PCI option
register clears the register's new value and subsequently leads to
re-writing the old value.
