apalis-tk1: fix pcie reset for reliable gigabit ethernet operation
It turns out that the current PCIe reset implementation in the PCIe
board init function is not quite working reliably due to PCIe reset
timing violations. Fix this by overriding the
tegra_pcie_board_port_reset() function.
Also allow optionally bringing up the PCIe switch as found on the Apalis
Evaluation board. Note however that the Apalis PCIe port is also left
disabled in the device tree by default.

arm: tegra: initial support for apalis tk1
This patch adds board support for the Toradex Apalis TK1 a computer on
module which can be used on different carrier boards.
The module consists of a Tegra TK1 SoC, a PMIC solution, 2 GB of DDR3L
RAM, a bunch of level shifters, an eMMC, a TMP451 temperature sensor
chip, an I210 gigabit Ethernet controller and a SGTL5000 audio codec.
Furthermore, there is a Kinetis MK20DN512 companion micro controller for
analogue, CAN and resistive touch functionality.
For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.
The following functionality is working so far:
- eMMC boot, environment storage and Toradex factory config block
- Gigabit Ethernet
- MMC/SD cards (both MMC1 as well as SD1 slot)
- USB client/host (dual role OTG port as client e.g. for DFU/UMS or host,
other two ports as host)
