The 'interrupt-names' property is not described in dtschema, not used by
the driver and does not really make sense as its value is simple 'irq'.

Device tree schema expects regulator names to be lowercase.  Changing to
lowercase has multiple effects:
1. LDO6 supply is now properly configured, because regulator driver
   looks for supplies by lowercase name,
2. User-visible names via sysfs or debugfs are now lowercase,
2. dtbs_check warnings are fixed:

There are two type of i.MX8MM EVK board, one is populated with
LPDDR4(default dts), and one is populated with DDR4. these two
boards share most of the board design, but still have some difference.
imx8mm-evk has emmc support, imx8mm-ddr4-evk has gpmi nand support.
And also, the BT/WIFI module is different. So move the common dts
part into imx8mm-evk.dtsi for reuse.

The SP805 binding sets the order of the clock-names to be: "wdog_clk",
"apb_pclk" (in exactly that order).

Change the order in the DTs for Freescale platforms to match that. The
two clocks given in all nodes are actually the same, so that does not
change any behaviour.
