pch_get_version op was only used by the ich spi controller driver,
and does not really provide a good identification of pch controller
so far, since we see plenty of Intel PCH chipsets and one differs
from another a lot, which is not simply either a PCHV_7 or PCHV_9.
Now that ich spi controller driver was updated to not get such info
from pch, the pch_get_version op is useless now.

At present this SPI driver works by searching the PCI buses for its
peripheral. It also uses the legacy PCI API.
In addition the driver has code to determine the type of Intel PCH that is
used (version 7 or version 9). Now that we have proper PCH drivers we can
use those to obtain the information we need.
While the device tree has a node for the SPI peripheral it is not in the
right place. It should be on the PCI bus as a sub-peripheral of the LPC
device.
Update the device tree files to show the SPI controller within the PCH, so
that PCI access works as expected.
