ARM: dts: msm: fix dt entry of gdsc_vdd-supply for fsm9900 



Recent change in pcie driver causes a mismatch of entry name between pcie
driver and fsm9900 device tree entry.  This patch fixes the mismatch.

Further more, this patch enables support of two PCIe Root Complex.

The gdsc_pcie_0 and gdsc_pcie_1 regulators are disabled. Dummy regulators
are used, since gdsc is not a collapsible domain in fsm9900.

pcie0_power_en_vreg and pcie1_power_en_vreg are set with regulator-boot-on
option, same as 8084 wlan_vreg.
