[PATCH] shpchp: fix improper reference to Mode 1 ECC Capability" bit

The hpc_get_mode1_ECC_cap() function of SHPCHP driver seems to refer
the wrong bit for refering the "Mode 1 ECC Capability" bit. This bug
seems not to cause any problem so far. But I think this should be
fixed. This patch fixes this bug.
