PCI: imx6: Fix IMX6SX_GPR12_PCIE_TEST_POWERDOWN handling
The IMX6SX_GPR12_PCIE_TEST_POWERDOWN bit does not control the PCIe
reference clock on i.MX6SX. Instead, it is part of i.MX6SX PCIe core
reset sequence.
Move the IMX6SX_GPR12_PCIE_TEST_POWERDOWN assertion/deassertion into
the core reset functions to properly reflect its purpose. Remove the
.enable_ref_clk() callback for i.MX6SX since it was incorrectly
manipulating this bit.
