Subject: [PATCH] HACK: Allwinner: Don't set up PMIC
There are two issues:
1. Regulators must be bring up in certain order with delays between
steps which are not considered here.
2. PMIC setup fails on board without PMIC, like Tanix TX6.
Since LibreELEC doesn't need things that need additional regulators to
be set up in U-Boot like networking, disable PMIC completely in order to
avoid above issues.
