00f917f52e atimach64gx: Add io_access_allowed. 
This method is used by both pci_io_read and pci_io_write to determine if ISA type I/O access is allowed.
The SPARSE_IO_BASE I/O address is defined. This I/O range is not defined by an I/O BAR.

6f231f3367 grandcentral: IOBus changes. 
- Add IOBusDevice (nvram_addr_hi_dev) for NVRAM addr hi.
- Add IOBusDevice (nvram_dev) for NVRAM data.
- Make all IOBusDevices use the same code.
- Log error if 4 least significant bits of offset are not zero.
- Correctly byte swap the value before passing it to the IOBusDevice.
- When reading, duplicate the bytes in a word or dword like a real Power Mac does.

7b4d513e22 videoctrl: Add change resolution support. 
PDM defaults to 640x480.
If you set --mon_id to MacRGB12in then it would draw 512x384 inside a 640x480 window.
If you set --mon_id to Multiscan20in then it would try to draw 832x624 inside a 640x480 window and crash.
If you set the Monitors control panel to switch multiscan display from 640x480 to 832x624 and  restart then it would crash.
Now it will correctly change the window size every time the mode changes.

d686fc04f4 atirage: Fix crtc_update.

9aef78be4f atirage: Modify write CLOCK_CNTL. 
Consider write-only bits: ATI_CLOCK_STROBE can't be read so clear it.
8 bits at Offset 2 is PLL_DATA. If we don't modify PLL_DATA, then insert the current value of PLL_DATA into the value that will be read from ATI_CLOCK_CNTL.
