Adopt the SPDX license identifier headers to ease license compliance
management.
Most of the wandboard dts files have already been converted, so switch
the remaining ones.

sgtl5000 codec needs MCLK clock to be present so that it can
successfully read/write via I2C.
In the case of wandboard, MCLK is provided via
MX6QDL_PAD_GPIO_0__CCM_CLKO1 pad.
Move the MCLK pinctrl from hog group to the codec group, so that the
codec clock can be present prior to reading the codec ID.
This avoids the following error that happens from time to time:
[ 2.484443] sgtl5000 1-000a: Error reading chip id -6

The rev C1 Wandboard uses the Broadcom 4330 for WiFi and Bluetooth instead of
the 4329. This changes the PADS assigned for the control lines. Another
side effect of the change is that on the rev C1 board, usdhc driver can't
detect the chip presence correctly so usdhc2 now needs its 'non-removeable'
property removed.
So that rev B1 and earlier can continue to work, this patch splits the
board-specific definitions from imx6qdl-wandboard.dtsi into
imx6qdl-wandboard-revb1.dtsi and imx6qdl-wandboard-revc1.dtsi. The new files
include the original base imx6qdl-wandboard.dtsi which retains the common
definitions.
The existing imx6dl-wandboard.dts includes imx6qdl-wandboard-revc1.dtsi and
imx6dl-wandboard-revb1.dts (new) includes imx6qdl-wandboard-revb1.dtsi.
This makes the rev C1 board the new default. The same pattern is used for
imx6q-wandboard.dts.
So, from U-Boot on a WB-Quad you use imxq-wandboard-revb1.dtb for the older B1
board and imxq-wandboard.dtb for the current rev C1 board.
