Kunimitsu: Fix Wifi, kepler RP mapping and enable ClkReqSupport

(1) Wifi is connected on RP1 which is 1c.0 , so enabling
        1c.0 and disabling 1d.0
    (2) kepler is on RP5 which is 1c.4, so enabling it
    (3) enabling ClkReqSupport for RP1 and RP5 so that L1 substates can
        get enabled.

BRANCH=None
    BUG=chrome-os-partner:43738
    TEST=Built and boot for Kunimitsu. checked all PCIe powersaving
         states (LTR, L1, L1S) are enabled
