[PATCH] PCI: Fix bit definitions of PCI_EXP_LNKCAP2 register

From: Jingoo Han
Date: Fri Nov 09 2012 - 01:56:01 EST


According to the PCIe 3.0 spec, PCI_EXP_LNKCAP2_SLS_2_5GB is
1st bit of PCI_EXP_LNKCAP2 register, not 0th bit. So, the bit
definition of supported link speed vector should be fixed.
