Prior to this patch, any VT100 codes emitted by U-Boot are considered part
of a command's output, which often causes tests to fail. For example,
test_env_echo_exists executes printenv, and then considers any text on a
line before an = sign as a valid U-Boot environment variable name. This
includes any VT100 codes emitted. When the test later attempts to use that
variable, the name would be invalid since it includes the VT100 codes.
Solve this by stripping VT100 codes from the match buffer, so they are
never seen by higher level test code.
The codes are still logged unmodified, so that users can expect U-Boot's
exact output without interference. This does clutter the log file a bit.
However, it allows users to see exactly what U-Boot emitted rather than a
modified version, which hopefully is better for debugging. It's also much
simpler to implement, since logging happens as soon as text is received,
and so stripping the VT100 codes from the log would require handling
reception and stripping of partial VT100 codes.

On recent SoCs, tegra_pcie_phy_enable() isn't called; but instead

part of tegra_pcie_phy_enable() needs to happen in all cases. Move that
code to tegra_pcie_port_enable() instead.
For reference, NVIDIA's downstream Linux kernel performs this operation
in tegra_pcie_enable_rp_features(), which is called immediately after
tegra_pcie_port_enable(). Since that function doesn't exist in the U-Boot
driver, we'll just add it to the tail of tegra_pcie_port_enable() instead.

The value that should be programmed into the PADS_REFCLK register varies
per SoC. Fix the Tegra PCIe driver to program the correct values. Future
SoCs will require different values in cfg0/1, so the two values are stored
separately in the per-SoC data structures.
For reference, the values are all documented in NV bug 1771116 comment 20.
The Tegra210 value doesn't match the current TRM, but I've filed a bug to
get the TRM fixed. Earlier TRMs don't document the value this register
should contain, but the ASIC team has validated all these values, except
for the Tegra20 value which is simply left unchanged in this patch.
