pinctrl: make a copy of pinmux map
This makes a deep copy of the pinmux function map instead of
keeping the copy supplied from the platform around. This makes
it possible to tag the platforms map with __initdata as is also
done as part of this patch.
Rationale: a certain target platform (PXA) has numerous
pinmux maps, many of which will be lying around unused after
boot in a multi-platform binary. Instead, deep-copy the one
we're going to use and tag them all __initdata so they go away
after boot.
ChangeLog v1->v2:
- Fixup the deep copy, missed a few items on the struct,
plus mark bool member non-const since we're making runtime
copies if this stuff now.
ChangeLog v2->v3:
- Make a shallow copy (just copy the array of map structs)
as Arnd noticed, string constants never get discarded by the
kernel anyway, so these pointers may be safely copied over.
