[PATCH 32/33] dt: hisilicon: add support for the PMIC found on Hikey 970

From: Mauro Carvalho Chehab
Date: Tue Aug 11 2020 - 11:42:21 EST

Add a device tree for the HiSilicon 6421v600 SPMI PMIC, used
on HiKey970 board.

As we now have support for it, change the fixed regulators
used by the SD I/O to use the proper LDO supplies.

We'll keep the 3v3 fixed regulator, as this will be used
by the DRM/KMS driver. So, let's just rename it.
