crypto: ecc - Add nbits field to ecc_curve structure
Add the number of bits a curve has to the ecc_curve definition to be able
to derive the number of bytes a curve requires for its coordinates from it.
It also allows one to identify a curve by its particular size. Set the
number of bits on all curve definitions.
