The GENMASK is defined in multiple files (with various names such as MASKBIT), which sets certain consecutive bits to 1 and leaves the others to 0. To avoid duplicate macros, add GENMASK macro to helpers.h. GENMASK(high, low) sets bits from `high` to `low` (inclusive) to 1. For example, GENMASK(39, 21) gives us the 64-bit vector 0x000000ffffe00000. Remove duplicate macro definitions. Also utilize GENMASK for _BF_MASK in mmio.h.
