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.

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.

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.

because that will mean register reordering screwing up the return

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

At that time, U-Boot used separate .config files for U-Boot proper

Now, we have switched to single .config configuration.

My main motivations for this commit are:
[1] Follow the arch/arm/Makefile style of Linux Kernel
[2] Maintain compiler options systematically
Currently, we give -march=* and -mtune=* options inconsistently:
Only some of the CPUs pass -march=* and -mtune=* options.
By collecting such options into the single place arch/arm/Makefile
we can tell which options are missing at a glance.
[3] Prepare for deprecating arch/*/cpu/*/config.mk
Note:
This commit just moves the compiler options so as not to change
the behavior at all. It does not care about the correctness of
the given options. Fox example, "-march=armv5te" might be better
than "-march=armv4" for ARM946EJS, but it is beyond the scope this
commit. Also, filling the missing -march=* and -tune=* is left
to follow-up patches.

board/sunxi/board.c tries to set ldo3 to 2.8v however drivers/power/axp209.c
contains an incorrect limit on ldo3 of 2.275v
The origin of the incorrect limit seems likely due to some inconsistencies
in the axp209 datasheet. ldo3 is described with different limits in
different sections. register 0x29 uses 7 bits for voltage configuration
while the 2.275v limit would apply if only 6 bits were used.
Probably this is a cut&paste error from register 0x23
The linux kernel driver has the correct limit and operation up to the 2.8v
required by my board has been physically verified with a multimeter.

Of 4 boards in our automated test system 2 do not have reliable
networking with the default TX delay of 0x0. Increasing to 0x1 seems
to make things reliable on all 4 boards.
Some previous ad-hpoc tests with tx delay set to 0, 1, 2 and 3 on one
of the problematic boards showed:
0: mw.l 0x1c20164 0x006 1 -- t/o in 4/5 tftp runs
1: mw.l 0x1c20164 0x406 1 -- t/o in 1/5 tftp runs
2: mw.l 0x1c20164 0x806 1 -- t/o in 1/5 tftp runs
3: mw.l 0x1c20164 0xc06 1 -- t/o many times in first tftp run
For 0, 1 and 2 "t/o" means one or two "T" glitches in the download,
but it did complete. For 3 those were basically continuous and it
couldn't complete.
tftp was of a 16M initrd.
