To make the usage of this function more flexible, lets add the CRC start value as parameter to this function. This way it can be used by other functions requiring different start values than 0 as well.
For non-zero CRC start values to work, I've reworked the function a bit. The new implementation is copied from the Linux version in drivers/i2c/i2c-core.c / i2c_smbus_pec(). Which supports non-zero CRC stating values.
I've double-checked that the results for zero starting values are identical to the results from the original version of this function.

Applied to u-boot/master, thanks!
