Document these widely used functions.
Update kernel-api.rst to point to the correct place, instead of to
crc32-main.c which no longer contains kerneldoc comments.
Simplify the documentation in crc32poly.h to just point to the
corresponding functions, now that they are properly documented. Change
the value of CRC32C_POLY_LE to lower case, for consistency.

Header was defining CRCPOLY_LE/BE and CRC32C_POLY_LE but in fact all of
them are CRC-32 polynomials so use consistent naming.

Allow other drivers and parts of kernel to use the same define for
CRC32 polynomial, instead of duplicating it in many places. This code
does not bring any functional changes, except moving existing code.
