Subject: [PATCH AUTOSEL 5.7 35/58] ARM: dts: sunxi: bananapi-m2-plus-v1.2: Add regulator supply to all CPU cores

From: Chen-Yu Tsai <wens@...e.org>

[ Upstream commit 55b271af765b0e03d1ff29502f81644b1a3c87fd ]

The device tree currently only assigns the a supply for the first CPU
core, when in reality the regulator supply is shared by all four cores.
This might cause an issue if the implementation does not realize the
sharing of the supply.

Assign the same regulator supply to the remaining CPU cores to address
this.
