ahci: Fix a wrong parameter pass
In stead of user_buffer_size, transfer_size should be used to pass to
ahci_device_data_io(). transfer_size is the length that we want the
low level function to transfer each time.
If we use user_buffer_size which is the totally data length as parameter,
low level function will actually create many SGs to transfer as many data
as possible each time. That will produce many redundant data transfer.

env_sf: Fix recovery default
The u-boot environment is redundantly stored in a NOR flash on our boards.
Redundant means that there are two places to store the environment. But only
one of the two is active. I discovered that on one board the u-boot (env_sf)
uses the environment from the second place and the Kernel (fw_printenv) uses
the environment from the first place.
To decide which is the active environment there is a byte inside the
environment. 1 means active and 0 means obsolete. But on that board both
environments had have a 1. This can happen if a power loss or reset occurs
during writing the environment. In this situation the u-boot (env_sf)
implementation uses the second environment as default. But the Kernel
(fw_printenv) implementation uses the first environment as default.
This commit corrects the default in the u-boot env_sf implementation when a
problem was detected. Now the recovery default is the same like in all other
environment implementations. E.g. fw_printenv and env_flash. This ensures that
u-boot and Kernel use the same environment.

if the requested page number is not currently in the buffer. When
a block is erased, the page number is marked as invalid if the
erased page equals the one currently in the cache. However, since
a erase block consists of multiple pages, also other page numbers
could be affected.
The commands to reproduce this issue (on a written page):

> nand dump 0x800
The second nand dump command returns the data from the buffer,
while in fact the page is erased (0xff).
Avoid the hassle to calculate whether the page is affected or not,

vexpress64: cut config and defaults for unclear variant
This variant that is neither FVP / Base Model or Juno Versatile
Express 64bit is confusing. Get rid of it unless someone can
point out what machine that really is. Seems to be an evolutional
artifact in the config base.

armv8: semihosting: delete external interface
Now that loading files using semihosting can be done using
a command in standard scripts, and we have rewritten the boardfile
and added it to the Vexpress64, let's delete the external
interface to the semihosting file retrieveal and rely solely
on these commands, and staticize them inside that file so the
whole business is self-contained.

vexpress64: remove board late init, use smhload
This removes the kludgy late board init from the FVP simulator
version of Versatile Express 64bit (ARMv8), and replace it with
a default boot command using the new smhload command to load
the files using semihosting. Tested on the Foundation Model.

armv8: semihosting: add a command to load semihosted images
Instead of sprinkling custom code and calls over the Vexpress64
boardfile, create a command that loads images using semihosting
just like we would load from flash memory of over the network,
using a special command:
smhload <image> <address>
This will make it possible to remove some custom calls and
code and make the boot easier.

armv8: semihosting: do not inline trap call
The semihosting trap call does not like being inlined, probably
because that will mean register reordering screwing up the return
value in r0, so tag this function "noinline".

Document config_distro_bootcmd environment variables for interactive booting.
config_distro_bootcmd.h defines a common boot environment for multiple
platforms, including several environment variables that are intended for
interactive use by an end-user. Document which variables are considered
public interfaces that must remain compatible in future u-boot versions.

board/BuR/common: move I2C initialization from common part to board-specific
At this time I2C and responsible pin-mux is setup during PMIC initialziation
within common.c, this is possible because today PMIC is always connected on
I2C0.
In Future this will be changed, PMIC isn't anymore connected to bus0 in call
cases.
So we do following:
- rename enable_i2c_pin_mux0 to enable_i2c_pin_mux to be generic for enabling
pin-mux on different or more busses.
- move the call to i2c_pin_mux and i2c_init from common.c to the specific
board.c
