ARM: dts: exynos: Fix eMMC regulator properties on Odroid U3 boards
LDO20 regulator provides power for the MMC card on Odroid U3 boards. That
regulator has been marked as 'boot-on' since the beginning of Odroid X/U3
support, but such flag is not really needed for it. That regulator is
correctly described as supply for eMMC card and controlled by its driver.
Commit 05f224ca6693 ("regulator: core: Clean enabling always-on regulators
+ their supplies") changed the way the boot-on regulators are handled and
since then regulators marked as 'boot-on' got increased reference count
and are not turned off for the system suspend time.
The new approach turned out to break suspend/resume support on Odroid U3
with eMMC card, because the card is not properly shutdown due to missing
of power cycle. Fix this by removing excessive 'boot-on' flag and let
MMC driver to control turning power on and off.
