spi: Update for v6.2
One more last minute patch for v6.2 updating the parsing of the
newly added spi-cs-setup-delay-ns - it's been pointed out that
due to the way DT parsing works the change in property size is
ABI visible so let's not let a release go out without it being
fixed. The change got split from some earlier ABI related fixes
to the property since the first version sent had a build error.
spi: Use a 32-bit DT property for spi-cs-setup-delay-ns
65us is not a reasonable maximum for this property, as some devices
might need a much longer setup time (e.g. those driven by firmware on
the other end). Plus, device tree property values are in 32-bit cells
and smaller widths should not be used without good reason.
Also move the logic to a helper function, since this will later be used
to parse other CS delay properties too.
