Subject: [PATCH 1/2] arm64: dts: ti: k3-am62a7-sk: Add boot phase tag for USB0

The USB0 instance of USB on AM62Ax SoC can be used for USB DFU boot. This
requires USB0 to be enabled at all stages of the boot process. In order to
support USB DFU boot on AM62A7-SK, add the "bootph-all" property to USB0.
