[PATCH FIXUP] pinctrl: mvebu: fixup mpp_base check

[Sebastian Hesselbarth]

Sascha,

unfortunately, your dev_request_mem_region fixup introduced a typo
(map_base instead of mpp_base). I took the chance to also add a
corresponding check for dove's pinctrl stub.

Please squash into commmit 8d3f0c2496afe397667e35ff6b94153bcecdb6ad
 ("pinctrl: mvebu: add pinctrl drivers for Dove and Kirkwood")

Thanks!
