ENGR00325255 pcie:enable pcie support on imx6sx sd
Enable pcie support in uboot on imx6sx sd boards
- enable_pcie_clock should be call before ssp_en is set,
since that ssp_en control the phy_ref clk gate, turn on
it after the source of the pcie clks are stable.
- add debug info
- add rx_eq of gpr12 on imx6sx
- there are random link down issue on imx6sx. It's
pcie ep reset issue.
solution:reset ep, then retry link can fix it.
