The GPIO polarity is missing in the cd-gpios property.

Fix it, so that the following build warning is gone:

  DTC     arch/arm/boot/dts/imx35-eukrea-mbimxsd35-baseboard.dtb
arch/arm/boot/dts/imx35-eukrea-mbimxsd35-baseboard.dtb: Warning (gpios_property): cd-gpios property size (8) too small for cell size 2 in /soc/aips@53f00000/esdhc@53fb400

The correct property name is 'interrupt-parent', so fix it accordingly.

On imx6sx accessing OCOTP directly is wrong because the ocotp clock
needs to be enabled first. Use the nvmem-cells binding instead.

This requirement does not apply to older imx6qdl chips because there the
ocotp access clock (clk_ipg_s) is always enabled.

This is visible by comparing the "System Clocks, Gating, and Override"
tables (OCOTP rows) in the 6DQ and 6SX manuals:
http://www.nxp.com/assets/documents/data/en/reference-manuals/IMX6SXRM.pdf
http://www.nxp.com/assets/documents/data/en/reference-manuals/IMX6DQRM.pdf

This happens to work right now because the ocotp clock might be enabled
for some other reason. In particular the it might be enabled from the
bootloader and it only gets disabled late during boot in
clk_disable_unused, after imx-thermal has completed probing.

If imx-thermal is compiled as a module then the system can hang on
probe.

By default, the lcdif_pre_sel mux is switched to the pll3_pfd1_540m PFD
source. If this mux is allowed to propagate rate changes to its parent,
setting the LCDIF pixel clock rate to 9 MHz, as required by the LCD
panel, will cause the pll3_pfd1_540m PFD to be switched away from its
nominal rate to 288 MHz.
This has no negative side effects, as there are no other children to
this PFD. Still, to avoid surprises, it might be preferrable to switch
to the designated video PLL (pll5_video_div) as clock source for the
LCDIF pixel clock.
