Subject: [PATCH] tools/power/x86/intel-speed-select: Remove duplicate macro

There are some macros such as `GENMASK` and `GENMASK_ULL` are redefined in
`include/linux/bits.h`. Simultaneously, the `GENMASK` in
`include/linux/bits.h` is more secure and prevents the following situation.
1. [net: stmmac: Fix misuses of GENMASK macro](https://reurl.cc/loMWvl)
2. [clocksource/drivers/npcm: Fix misuse of GENMASK macro](
https://reurl.cc/b2yr96)

Therefore, I think these macro could be removed.
