docs: clean up and add rest of CRC functions to kernel-api.rst

Browse Source 
Add the rest of the CRC library functions to kernel-api.

- try to clarify crc32() by adding '@' to a function parameter
- reorder kernel-api CRC functions to be less random
- add more CRC functions to kernel-api
- correct the function parameter names in several places

* crc32_generic_shift - Append len 0 bytes to crc, in logarithmic time
* crc32_generic_shift - Append @len 0 bytes to crc, in logarithmic time
* @crc: The original little-endian CRC (i.e. lsbit is x^31 coefficient)
* @len: The number of bytes. @crc is multiplied by x^(8*@len)
* @polynomial: The modulus used to reduce the result to 32 bits.
