The Sige5 uses two fusb302 controllers, one of which is on the USB Type
C power input connector. Add this controller to the Sige5's u-boot
specific tree, as it is critical that it is initialised before Linux
takes over, so that it does not kill the power input once someone adds
the fusb302 node to its device tree.

Also enable the necessary FUSB302 u-boot driver in the Sige5's defconfig.

The BootROM on RK3576 has an issue loading boot images from an SD-card.
This issue can be worked around by injecting an initial boot image
before TPL that:

  writel(0x3ffff800, 0x3ff803b0)

Prepend an image containing binary code that does this and return to
BootROM to load next image, TPL.

TODO: embed the binary code into rkcommon.c

As the name implies, it is built around the RK3576 SoC with 4x Cortex-A72
cores, four Cortex-A53 cores and Mali-G52 MC3 GPU.

Storage options are EMMC, SD-Card, a 2242 M.2 slot and the possibility to
use UFS 2.0 storage.

Video Output options are a HDMI port, a DSI connector as well as Display-
Port via the TypeC connector (all of them not yet supported).

Networking options are a Low-profile Gigabit Ethernet RJ45 port with
Motorcomm YT8531 PHY as well as WiFi via an AMPAK AP6256 module.

USB ports on the board are 1x USB 3.0 port, 1x USB 2.0 port, 1x USB Type-C
and it comes with 40-pin GPIO header

The rk3576 uses a different base-compatible, as starting with this
generation, the clock phase tuning is done via registers inside
the mmc controller and not from inside the CRU.

In U-Boot we do not tune at all, so no other code changes are
necessary.

The current DT bindings for the rk3576 clock use a different ID than the
one that is supposed to be written to the hardware registers.
Thus, we cannot use directly the id provided in the phandle, but rather
use a lookup table to correctly setup the hardware.

This follows the implementation done in the Linux-Kernel and also
how the rk3588 does this both in the Linux-Kernel as well as U-Boot.
