[PATCH v2 5/5] PCI/ASPM: Remove unnecessary ASPM_STATE_L1SS check

[Ajay Agarwal <ajayagarwal@google.com>]

Currently the driver checks if ASPM_STATE_L1SS is supported
before calling aspm_calc_l12_info(), only for this function to
return if ASPM_STATE_L1_2_MASK is not supported. Simplify the
logic by directly checking for L1.2 mask.

Changelog since v1:
 - Rebase on top of the L1.2 function rename patch
