powerpc/pseries/mce: Fix misleading print for TLB mutlihit
On pseries, TLB multihit are reported as D-Cache Multihit. This is because the wrongly populated mc_err_types[] array. Per PAPR, TLB error type is 0x04 and mc_err_types[4] points to "D-Cache" instead of "TLB" string. Fixup the mc_err_types[] array. Machine check error type per PAPR: 0x00 = Uncorrectable Memory Error (UE) 0x01 = SLB error 0x02 = ERAT Error 0x04 = TLB error 0x05 = D-Cache error 0x07 = I-Cache error Fixes: 8f0b80561f21 ("powerpc/pseries: Display machine check error details.")
