[PATCH] Revert "ARM: dts: sunxi: Add regulators for Sinovoip BPI-M2"

[Icenowy Zheng]

This reverts commit 7daa213700758b5b08fc0daab09bb139dd334165.

The original commit has several problems:

- vdd-cpus and aldo3 (AVCC of the SoC) are not set to always-on, which
leads to system hang when disabling unused regulators.
- GMAC (which uses dldo1 and aldo2) and Wi-Fi (which uses aldo1) are not
considered, and will fail to work after adding this commit.

This indicates that this patch should be not tested at all.
