ARM: dts: apq: Add USB OTG support for APQ8096 DragonBoard



USB OTG mode depends on USB ID detection performed by the PMIC driver.
APQ8096 DragonBoard SOMs use either a PMI8994 or a PMI8996 component.
In PMI8994, USB ID detection is based on an interrupt handled by the
qpnp-smbcharger driver, so the pmi8994_charger device tree node
must be enabled.
In PMI8996, pmi8994_fg device needs to be enabled as well, as the charger
USB ID detection is not connected to any interrupt, but handled by the
qpnp-fg driver.
Additionally, remove USB PHY initialization which causes USB PHY PLL
lock failure.
