fs/ufs: use ktime_get_real_seconds for sb and cg timestamps

get_seconds() is deprecated because of the 32-bit overflow and will be
removed. All callers in ufs also truncate to a 32-bit number, so
nothing changes during the conversion, but this should be harmless as
the superblock and cylinder group timestamps are not visible to user
space, except for checking the fs-dirty state, wich works fine across
the overflow.

This moves the call to get_seconds() into a new inline function, with a
comment explaining the constraints, while converting it to
ktime_get_real_seconds().

ASoC: Fixes for v4.15

This is a fairly large set of fixes, they've been delayed partly as more
and more keep coming in. Most of them are very small driver specific
fixes, the biggest individual thing is the revert of the rcar IOMMU
support - it was causing problems and there wasn't the confidence that
it could be resolved sensibly. There's also a relatively large change
in the Freescale SSI controller which resolves some issues with the
AC'97 mode, these aren't that large in the grand scheme of things and
reflect some fairly thorough review and testing.
