spi: spi-qpic-snand: cleanup 'qpic_ecc' structure

Merge series from Gabor Juhos <j4g8y7@gmail.com>:

The series consist of two small patches to clean up the qpic_ecc structure
in the spi-qpic-snand driver. The first one removes an unused member from
the structure, whereas the second reduces code duplication and removes
another two members from the same.
