Now that the clock-frequency information has been moved to the
driver, more DT sync is possible.

In Linux, the clock rate of the UART is given by the clock driver.
If you try to follow that in U-Boot, you would end up with adding
more u-boot,dm-pre-reloc properties, and also the clock driver would
be too big for SPL, which is used for UniPhier ARMv7 platform.
The current solution is to add 'clock-frequency' property to the
UART nodes, but it does not exist in the DT files in Linux. I do
not want to let DT diverge for U-Boot.
Check the SoC compatible and set the clock rate according to it.
This will be helpful to sync DT between Linux and U-Boot.

Enable the on-chip ethernet driver for uniphier_{v7,v8}_defconfig.
Disable the on-board SMC911x because it has not migrated to the
driver model yet - it is not possible to enable DM and non-DM
drivers at the same time.
The CONFIG_SMC911X for uniphier_ld4_sld8_defconfig is still kept
because the on-chip ethernet driver for LD4, sLD8 is not supported
yet.

As many targets are now commonly built with gcc-6 or later (which
defaults to a newer C standard than older compilers), certain C
constructs are now being used as they produce more readable code. And
while all compilers that we support building with support the C11
standard (and GNU11) they do not default to that standard. Ensure that
we pass along -std=gnu11 when building.

The ARM64 has 2 MiB alignment requirement for the kernel. When using
fitImage, this requirement may by violated, the kernel will thus be
executed from unaligned address and fail to boot. Do what booti does
and run booti_setup() for kernel_noload images on arm64 to obtain a
suitable aligned address to which the image shall be relocated.

Add option to the booti_setup() which indicates to it that the caller
requires the image to be relocated to the beginning of the RAM and
that the information whether the image can be located anywhere in RAM
at 2 MiB aligned boundary or not is to be ignored. This is useful ie.
in case the Image is wrapped in another envelope, ie. fitImage and not
relocating it but moving it would corrupt the envelope.

Do not stop the clock in the start callback in case of failure, keep
them running to also keep the PHY running. The failure could be ie.
PHY failing to negotiate link and if the clock get shut down, another
attempt at bringing the link up would fail. The clock right now are
started in probe function and stopped in remove function, which is
the correct behavior.

This is the case when reading freshly created filesystem.
The error message is like the following:
btrfs_read_superblock: No valid root_backup found!
Since the data from super_roots/root_backups is not actually used -
decided to rework btrfs_newest_root_backup() into
btrfs_check_super_roots() that will only check if super_roots
array is valid and correctly handle empty scenario.
As a result:
* btrfs_read_superblock() now only checks if super_roots array is valid;
the case when it is empty is considered OK.
* removed root_backup pointer from btrfs_info,
which would be NULL in case of empty super_roots.
* btrfs_read_superblock() verifies number of devices from the superblock
itself, not newest root_backup.
