arm: mvebu: theadorable: Add PEX-switch detection and reset code
Sometimes the PCIe link for the PEX-switch will not come-up. In this case, the board is not in a usable state. This patch makes sure that in this case a soft-reset is issued. If this soft-reset does not result in the PEX-switch being detected after some soft-reset cycles, an I2C message is sent to the uC to issue a complete power-cycle of the board.
