mtd: brcmnand: Add support for v6.2 controllers
Document and match the brcm,brcmnand-v6.2 compatible string, the controller has a register layout identical to the v6.0 version and supports prefetch. Update the command shift logic to account for v6.2 controller which are the first ones to use a shift of 0 (6.1 used a shift of 24).
