Yu-Ping Wu 941db0e55c helpers: Add GENMASK macro
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.
