This is not a bug actually but it is not obvious because there was a separate definition added in bcm_sf2_regs.h for port 8 named CORE_IMP_CTL. The logic in b53_regs.h is: #define B53_PORT_CTRL(i) (0x00 + (i)) and due to the memory map used in bcm_sf2, that would translate into: 8 << 2 = 0x20 which is correct here and matches the definition of CORE_IMP_CTL. in fact, the new code is more correct because any port could be a DSA CPU port, whereas before we assumed that port 8 == CPU port, which is not necessarily true.
