[PATCH v2 1/2] scripts: define le32_to_cpup and friends for host/target tools

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We already define le32_to_cpu and friends, but were missing so far the
p-suffixed variant, which accepts a pointer.

This is easily implemented with a bit of macro boilerplate, so let's do
that.
