Fix FAPI CoreSetType enumeration options after the fix on the description made by SCF

SCF FAPI 222.10.02 had a bug on the description of CoreSetType:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of CRB0 for DMRS mapping)
1: otherwise (subcarrier 0 of CORESET)

That was fixed in SCF 222.10.04:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of the CORESET)
1: otherwise (subcarrier 0 of CRB0 for DMRS mapping)

That wrong description created a misunderstanding, to overcome it we "wrongly" added a third value. This commit fixes that and aligns the CoreSetType with FAPI 222.10.04
