forked from mirrors/qmk_firmware
added config option: MATRIX_HAS_GHOST and fixed some on matrix.c
ADD: Build option: MATRIX_HAS_GHOST to enable ghost blocking logic. FIX: choose matrix buffer type(uint8_t/uint16_t) automatically depending on column size in matrix.c. FIX: use uint8_t insted of int in matrix.c.
