That caused the WLAN to stop working as the related .dts entries fell through the cracks. The legacy muxing was setting pulls for GPIO 48 and 49, so let's keep that behaviour for now to avoid further regressions for BT and FM. Also input logic was enabled for MMC CLK line, but I've verified that the input logic we don't need enabled for CLK line as it's not bidirectional. Also, we want to use non-removable instead of ti,non-removable as the ti,non-removable also sets no_regulator_off_init which is really not what we want as then wl12xx won't get powered up and down which is needed for resetting it. Note that looks like the WLAN interface fails to come up after a warm reset, but that most likely was also happening with the legacy booting and needs a separate fix.

That caused the WLAN to stop working as the related .dts entries fell through the cracks. I don't have the "1283 PG 2.21 connectivity device" on my 4430sdp, but the earlier version of this patch was tested by Luciano Coelho. This version has left out the input logic for MMC CLK line compared to the earlier version as that is not bidirectional, and should be safe to do.
