fix: fdt: a38x: fix I2C bus lock on DB-88F621-BP in LSP

	for boards with no USB VBUS signal that controlled via I2C IO expander,
	LSP was showing the following error on i2c:
	"mv64xxx_i2c f1011000.i2c: could not find pctldev for node
	/soc/internal-regs/pinctrl/i2c-pins-0, deferring probe
	platform f1011000.i2c: Driver mv64xxx_i2c requests probe deferral"

	- remove 'i2c-pins-0' when IO expander VBUS pins doesn't exist
	- remove 'xhci0-vbus-pins' when USB VBUS GPIOS pins doesn't exist
	- fixed JIRA:SYSTEMSW-1753
