i945: Use nullptr instead of NULL

nullptr was introduced in C11 spec and gcc 4.7.

    https://en.cppreference.com/w/cpp/language/nullptr
    https://stackoverflow.com/questions/16256586/how-to-enable-c11-on-later-versions-of-gcc

coreboot switched to GCC 4.7.2 on October 25, 2021, prior to coreboot v4.1.

    https://review.coreboot.org/c/coreboot/+/1609

GCC-13 implemented nullptr constant: https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3042.htm
So use it insted of NULL macro.
