ARM: dts: move hi6421 into dedicated dtsitopic-regulator-upstream-2

Move Hi6421 PMIC related device tree source into a dedicated dtsi.

Hi6421 is a PMIC SoC that can be reused in various Hi3620 based
boards.

Note: This file is supposed to be included in a board DTS that will
create the pmic node in order to allow the &pmic reference to work.

Exmaple:
...
        pmic: pmic@fcc00000 {
                reg = <0xfcc00000 0x0180>; /* 0x60 << 2 */
        };
...

/include/ "hi6421.dtsi"
...
