Subject: include/linux/bitops.h: introduce BITS_PER_TYPE
Patch-mainline: v4.19-rc1
Git-commit: 9144d75e22cad3c89e6b2ccab551db9ee28d250a
References: bsc#1136345 jsc#SLE-4681

net_dim.h has a rather useful extension to BITS_PER_BYTE to compute the
number of bits in a type (BITS_PER_BYTE * sizeof(T)), so promote the macro
to bitops.h, alongside BITS_PER_BYTE, for wider usage.
