board: ti: am335x: Fix scale_vcore for beaglebones
commit 0650798824 ("board: am335x: Introduce scale_vcores")
updated voltages of each board based on efuse. It updated
beagle bone specific voltages under the condition board_is_bone().
But this is true only for BeagleBoneWhite. Due to which voltages
are not configured for BBB, BBW as wrong device is being probed.
So create a common function board_is_beaglebonex() which includes
am335x based beagle family. Use this for updating voltages.
Also remove extra if condition for selecting voltages which is
done later using a switch case and match usb current limit as
before the commit 0650798824.
