Init RGB Matrix EEPROM

I'm not sure how to check if it's the same as RGBLIGHT's EEPROM, but if you don't init it, it **will not** work properly until it is initialized.

 The EEPROM for it is currently shared with the RGBLIGHT system (it's generally assumed only one RGB would be used at a time), but could be configured to use its own 32bit address with:
 
 ```C
-#define EECONFIG_RGB_MATRIX (uint32_t *)16
+#define EECONFIG_RGB_MATRIX (uint32_t *)28
 ```
