Subject: [PATCH 4.14 28/68] ARM: dts: imx6: pbab01: Set vmmc supply for both SD interfaces

From: Stefan Riedmueller <s.riedmueller@...tec.de>

[ Upstream commit f57011e72f5fe0421ec7a812beb1b57bdf4bb47f ]

Setting the vmmc supplies is crucial since otherwise the supplying
regulators get disabled and the SD interfaces are no longer powered
which leads to system failures if the system is booted from that SD
interface.
