* Merging early because of build failures. See #8105 * Make LPC1768 pinmapping not specific to Re-ARM * Add HAL_PIN_TYPE and LPC1768 pin features * M43 Updates * Move pin map into pinsDebug_LPC1768.h * Incorporate comments and M226 * Fix persistent store compilation issues * Update pin features * Update MKS SBASE pins * Use native LPC1768 pin numbers in M42, M43, and M226
