Fix two races in the timer stats lookup code.  One by ensuring that the

The other by cleaning up the hash table when the entries array is cleared,

The value T2_DENSE_MEM is now subtracted from the "xaddr" argument in
each of the readX/writeX routines, since those routines may be called
directly, rather than always through the ioreadNN/iowriteNN routines.

This code replaces earlier and incomplete handling of graphics on non-zero PCI
domains (aka hoses or peer PCI buses).

An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a
kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose
SRM consoles are capable of configuring and handling graphics options on
non-zero hoses.  All other machines have the option set FALSE.

A routine, "find_console_vga_hose()", is used to find the graphics device
which the machine's firmware believes is the console device, and it sets a
global (pci_vga_hose) for later use in managing access to the device.  This is
called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a
custom version of this routine because of extra complexity.

A routine, "locate_and_init_vga()", is used to find the graphics device and
set a global (pci_vga_hose) for later use in managing access to the device, in
the case where "find_console_vga_hose" has failed.

Various adjustments are made to the ioremap and ioportmap routines for
detecting and translating "legacy" VGA register and memory references to the
real PCI domain.

When either rx_buf or tx_buf is not being used, i.e.  for plain read- or
write operations, the atmel_spi uses a fixed-size DMA buffer instead.  If
the transfer is longer than the size of this buffer, it is split into
multiple DMA transfers.

When the transfer is split like this, the atmel_spi driver ends up using
the same DMA address again and again even for the buffer that came from the
user, which is of course wrong.  Fix this by adding the number of bytes
already transferred to the DMA address so that the data ends up in the
right place.
