Revision 1.0 of this IP has a couple of issues, such as not supporting
repeated start conditions for read transfers.
So scan through the list of i2c messages for these conditions
and report an error if they are attempted.
This has been fixed for revision 1.4 of the IP, so only report the error
when the IP can really not do it.

For mux check if the parent is already a device of UCLASS_I2C and if yes
just use that. Otherwise see if someone specified an i2c-parent phandle.
This mimics the behavior found in the Kernel, as it removes the
requirement to explicitly specify a i2c-parent phandle.

Initialize SBC and Support Card in U-Boot proper instead of SPL.
We may run different firmware (ex. ARM Trusted Firmware) before
U-Boot, and basic SoC initialization may be done there. In that
case, SPL may not be used.
The motivation for preparing SBC and Support Card in SPL was to use
LED for early debugging, but this is not mandatory to boot SoCs.
With this commit, LED will be unavailable in SPL, but we can use a
debug serial instead. So, this change will not be a big deal.

Right now the SPL is trying to load u-boot based on defines, i.e. one

or CONFIG_SPL_SPI_LOAD to boot from SPI FLASH, etc...
This prevent us from having a single SPL image that is able to boot from
all media, and one need to build an image for each medium. This
commit is replacing the #ifdef that select the boot medium by reading
the value of the boot pins (via the BOOTCFG register).
Now a single SPL image will be able to read from the boot pin to know
which device should be used to load u-boot.

When using ARMv8 with ARMV8_SPIN_TABLE=y, we want the slave cores to
wait on spin_table_cpu_release_addr, until the Linux kernel will "wake" them
by writing to that location. The address of spin_table_cpu_release_addr is
transferred to the kernel using the device tree that is updated by
spin_table_update_dt().
However, if we also use SPL, then the slave cores are stuck at
CPU_RELEASE_ADDR instead and as a result, never wake up.
This patch releases the slave cores by writing spl_image->entry_point to
CPU_RELEASE_ADDR location before the end of the SPL code
(at jump_to_image_no_args()).
That way, the slave cores will start to execute the u-boot and will get to
the spin-table code and wait on the correct address
(spin_table_cpu_release_addr).
