From: Sumit Garg <sumit.garg at oss.qualcomm.com>
The default DIP switch configuration on RB1/2 is to enable flashing
support via USB type-c port either using QDL or fastboot. It's just
cumbersome to get the host mode working in U-Boot via DIP switch toggle
when you need the flashing capability using the type-c port.
So instead lets enable fastboot in U-Boot for RB1/2 boards which is
more useful in the default board DIP switch configuration. This let's
us to drop dr_mode DT fixup.
