backports: bump kernel reqs for WL1251_SDIO and WLCORE_SDIO

There has been quite a bit of updates to the gpio driver library,
and while we can backport some of this it doesn't make much sense
as folks using this driver are expected to be carrying over the
required architecture changes. In particular the GPIO_DEVRES has
been tucked under GPIO_LIB and later removed from depending on it
(see b69ac5244 and 6a89a314a)
