Baytrail: Change PCIe root disable algorithm

Disable Root Port0 only when there is no PCIe device
present on any root port.

BUG=None
TEST=Boot Rambi with PCIe installed/non-installed on RP0 to
confirm the RP0 is correctly enabled/disabled. However, I still
need someone to help check if RP0(no device) is still enabled
if there is device on other RPs since since I have no devices
having slots from RP1/2/3.
