apalis_t30: fix optional pcie port reset for reliable pcie operation
Allow optionally bringing up the Apalis type specific 4 lane PCIe port
as well as the PCIe switch as found on the Apalis Evaluation board. In
order to avoid violating the PCIe reset timing do this by overriding the
tegra_pcie_board_port_reset() function. Note however that both the
Apalis type specific 4 lane PCIe port as well as the regular Apalis PCIe
port are also left disabled in the device tree by default.
