The actual configuration in uboot.env.txt has diverged from our
documentation (both the current and coming documentation). The
documentation have "better" names etc, therefore put we put back the
naming of the original configuration.

In TF-A in the commit:
   (5341b42ec) rpi3: Add mem reserve region to DTB if present

they started to runtime patching of the DTB, but the default build rules
in TF-A doesn't set RPI3_PRELOADED_DTB_BASE to anything which then gets
set to the default value: 1, which gives incorrect memory mappings for
MAP_BL32_MEM. Therefore we must tell where the DTB is located and we do
that by adding adding a compile time flag to TF-A, i.e.,

       RPI3_PRELOADED_DTB_BASE=0x00010000

1. Switch to upstream ARM Trusted Firmware and U-boot.
2. Change the ATF+OP-TEE booting sequence.

Now the booting sequence looks like:
VideoCore IV bootloader -> ATF + OP-TEE payload -> U-boot -> Linux kernel

1. Add Bus Bluster config/usage details
2. The Raspberry Pi 3 allows to enable JTAG on the GPIO via the
enable_jtag_gpio=1 flag in the config.txt, which is more prefarable.
Switch to this method
3. Add physical memory map
4. Change information about usage of Sequitur labs OpenOCD fork to
the uptsteam OpenOCD, as it already has ARMv8 support

U-boot dhcp/bootp client changes "serverip" variable value in case if it
was specified in a dhcp/bootp server configuration.
Renamed serverip var, which now is used for nfsboot target to avoid
updating of this value by DHCP/BOOTP clients and just to use our
pre-defined static value.
