soc/intel/apollolake: Properly disable PCIe root ports
1. The hotplug feature needs to be disabled
so that pcie root ports will be disabled by fsp
2. Correct PcieRootPortEn mapping.
The correct mapping should be like below
PcieRootPortEn[0] ==> 00:14.0
PcieRootPortEn[1] ==> 00:14.1
PcieRootPortEn[2] ==> 00:13.0
PcieRootPortEn[3] ==> 00:13.1
PcieRootPortEn[4] ==> 00:13.2
PcieRootPortEn[5] ==> 00:13.3
BUG=chrome-os-partner:54288
BRANCH=None
TEST=Checked pcie root port is disabled properly
and make sure pcie ports are coalesced.
Also make sure the device will still be enabled after coalescence
when pcie on function 0 is disabled devicetree
