Move the DSA switch configuration to the clearfog .dts file as this is
only present on the pro models.

There are two versions of the clearfog - a base and a pro model. The
base model has an additional PHY on eth1, replacing the DSA switch on
the pro model. MPP assignments are slightly different. The base model
also omits the second PCIe, and footprint for a PIC microcontroller.
In order to cater for these differences, move all the existing clearfog
support to a dtsi file before starting to modify it, to make the
following changes more clear.

The SPI flash #size-cells is specified in the binding documentation to
have value 1, but we were setting it to zero. This wasn't causing any
problem as we do not list any partitions, but it's worth specifying
correctly if we're going to specify it at all.

A static usb-serial-driver structure that is used to initialise the
interrupt URB was modified during probe depending on the currently
probed device type, something which could break a parallel probe of a
device of a different type.
Fix this up by overriding the default completion callback for MCS7715
devices in attach() instead. We may want to use two usb-serial driver
instances for the two types later.

There is a race window between write_cache_pages calling
clear_page_dirty_for_io and XFS calling set_page_writeback, in which
the mapping for an inode is tagged neither as dirty, nor as writeback.
If the COW shrinker hits in exactly that window we'll remove the delayed
COW extents and writepages trying to write it back, which in release
kernels will manifest as corruption of the bmap btree, and in debug
kernels will trip the ASSERT about now calling xfs_bmapi_write with the
COWFORK flag for holes. A complex customer load manages to hit this
window fairly reliably, probably by always having COW writeback in flight
while the cow shrinker runs.
This patch adds another check for having the I_DIRTY_PAGES flag set,
which is still set during this race window. While this fixes the problem
I'm still not overly happy about the way the COW shrinker works as it
still seems a bit fragile.
