rs780: Implement `rs780_internal_gfx_disable` and add .disable pcie_ops

    external PCIe card.

The following lines from function `rs780_internal_gfx_enable()` are
    taken and reversed.

    	l_dword &= ~(1<<0);
    	l_dword |= 1<<1;

It has been tested on the M4A785T-M with the following card inside the
