lynxpoint/broadwell: Correct L1 exit latency with ASPM

Lynx Point PCH reference code version 1.9.1 programs the larger L1 exit
latency when ASPM is enabled. Document 535127 (BDW PCH-LP BS) also does
the same. Correct the condition accordingly. On Lynx Point, also remove
a now-redundant write to the LCAP register (offset 0x4c).
