[PATCH] powerpc/pseries/mce: fix misleading print for TLB mutlihit.

[Mahesh J Salgaonkar <mahesh@linux.vnet.ibm.com>]

From: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>

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.")
