[PATCH 2/7] bitops: more BITS_TO_* macros

[Yury Norov]

Introduce BITS_TO_U64, BITS_TO_U32 and BITS_TO_BYTES as they are handy
in the following patches (BITS_TO_U32 specifically). Reimplement tools/
version of the macros according to the kernel implementation.

Also fix indentation for BITS_PER_TYPE definition.
