[PATCH AUTOSEL for 3.18 35/53] ARM: DRA7: clockdomain: Change the CLKTRCTRL of CM_PCIE_CLKSTCTRL to SW_WKUP

[Sasha Levin]

From: Kishon Vijay Abraham I <kishon@xxxxxx>

[ Upstream commit 2c949ce38f4e81d7487f165fa3b8f77d74a2a6c4 ]

The PCIe programming sequence in TRM suggests CLKSTCTRL of PCIe should be
set to SW_WKUP. There are no issues when CLKSTCTRL is set to HW_AUTO in RC
mode. However in EP mode, the host system is not able to access the
MEMSPACE and setting the CLKSTCTRL to SW_WKUP fixes it.
