[U-Boot] [PATCH] odroid: dts: change the buck8 min-microvolt value
Change the buck8's min-microvolt to 750000. Whent thor protocol is used, board_usb_init() should be tried to set to 750000. But it was returned -EINVAL, because '750000' too lower than 2850000. (thor command doesn't work fine because of this problem.)
