core_ca.h defines for ISR and SGIR_INTID

1. In core_ca.h, lines 644; 647; 650, the ISR_A_Pos, ISR_I_Pos, ISR_F_Pos should be not 13U, 12U, 11U, but 8U, 7U, 6U respectively, as per structure at lines 636-638.
2. In the same file, line 921, GICDistributor_SGIR_INTID_Msk should be not 0x7U, but 0xFU, as the INTID is 4 bits.
3. GICInterface_HPPIR_INTID_Msk should be 0x3FFU instead of 0xFFFFFFU.
