Add support for the last two remaining board variants and add SATA
support.

This is intended for the next branch.

[PATCH 1/4] board: sl28: move ethernet aliases to variant specific dtsi

[Michael Walle]

The variants differ in their network configuration. Move the first two
network aliases to the proper variant device tree includes. This is in
prepartion for variant 1 and 2 support which has a different network
port mapping. The network aliases for the two internal ports will stay
in the common dtsi because they are present on all board variants.

This might leave a hole if there is no ethernet1 alias. This is
intended.

[PATCH 2/4] board: sl28: add network variant 1 support

[Michael Walle]

This variant has one network port connected via RGMII and doesn't have
any TSN capabilities out-of-the-box. Instead it has all four SerDes
lanes available for customer use.

[PATCH 3/4] board: sl28: add network variant 2 support

[Michael Walle]

Although this variant has two external network ports, they are not (yet)
supported by the bootloader because they are connected via an internal
network switch. Otherwise its the same as the other variants.

[PATCH 4/4] board: sl28: add SATA support

[Michael Walle]

Enable SATA support. Although not supported by the usual SATA pins on
the SMARC baseboard connector, SATA mode is supported on a PCIe lane.
This way one can use a mSATA card in a Mini PCI slot.

We need to invert the received data because in this mode the polarity of
the SerDes lane is swapped. Provide a fixup in board_early_init_f() for
the SPL. board_early_init_f() is then not common between SPL and u-boot
proper anymore, thus common.c is removed, as it just contained said
function.
