ksz8021_config_init() unconditionally sets the KSZPHY_OMSO_RMII_OVERRIDE
bit. This is since the initial micrel phy commit, so it's not
reproducible where this comes from and why this is done. Neither U-Boot
nor the kernel ever touch this bit and so should we. Also, instead
of doing a write only operation, read/modify/write the bit we actually
want to change.
This fixes operation on a KSZ8081MLX which is a MII only phy.
KSZPHY_OMSO_RMII_OVERRIDE is reserved here and must be written to 0.
KSZPHY_OMSO_MII_OVERRIDE is default 1 and must be written as 1.

These structs are used for on-storage data layouts. They should be not
affected by different integer precisions and alignment optimizations of
32bit or 64bit machines. Using the architecture independent integer data
types, like uint32_t, achieves the former, using the packed attribute
the later.

This gets rid of some of the special cases in the bus scanning function
by splitting hierarchy enumeration and configuration and the actual
device registration into 2 passes.
This ensures that the PCI hierarchy below a root port is completely
set up before any device driver is probed.
This simplifies the code and makes it less error prone, while moving
the PCI address space layout closer to the one used by Linux.

This adds `filetype_squashfs` to the list of known filetypes and adds a
detection for squashfs files to file_detect_type(). This currently
matches on the `hsqs` start sequence of an image file.
Additionally, the newly introduced filetype is registered as the type of
the squashfs_driver which allows, for example, to mount squashfs without
the need to specify a type parameter.
This changes enable booting a squashfs with the simple `boot` command
pointing to the location (device) that holds the squashfs.
Note that booting with blspec is limited as the current squashfs driver
is not capable of handling symbolic links.

For builtin dtbs all compiled dtbs matching section .dtb.rodata.*
are collected in a single section. Since every dtb is compiled as
uncompressed and also as compressed binary each dtb ends up twice
in the section. Let's put the compressed variants in .dtbz.rodata.*
sections rather than .dtb.rodata.*.z so they end up in the binary
only once.
