There is a theoretical edge case during CPU_ON where the cache
may contain stale data for the target CPU data - this can occur
under the following conditions:

- the target CPU is in another cluster from the current
- the target CPU was the last CPU to shutdown on its cluster
- the cluster was removed from coherency as part of the CPU shutdown

In this case the cache maintenace that was performed as part of the
target CPUs shutdown was not seen by the current CPU's cluster. And
so the cache may contain stale data for the target CPU.

This patch adds a cache maintenance operation (flush) for the
cache-line containing the target CPU data - this ensures that the
target CPU data is read from main memory.

Migrate to Linaro release 17.04

ARM TF has been tested against Linaro Release 17.04 - the Linaro
binaries have been update and also the version of the compiler.

Linaro binaries: 17.01 --> 17.04
AArch64 & AArch32 compilers: 5.3-2015.05 (gcc 5.3) -> 6.2-2016.11 (gcc 6.2)

This patch updates the User Guide is to state that Linaro
release 17.04 is supported.

Additionally, the following fixes are made to the User Guide:
- Removed out of date reference to Linaro release 16.06.
- Updated the Juno variant coverage to include r2.

This patch fixes the two things as follows:

1) rk3399_flash_l2_b" seems to be a typo. That's "flush", not "flash".

2) fixes the warnings log.
We always hit the warnings thing during the suspend, as below log:
..
[   51.022334] CPU5: shutdown
[   51.025069] psci: CPU5 killed.
INFO:    sdram_params->ddr_freq = 928000000
WARNING: rk3399_flash_l2_b:reg 28830380,wait

When the L2 completes the clean and invalidate sequence, it asserts the
L2FLUSHDONE signal. The SoC can now deassert L2FLUSHREQ signal and then
the L2 deasserts L2FLUSHDONE.

Then, a loop without a delay isn't really great to measure time. We should
probably add a udelay(10) or so in there and then maybe replace the WARN()
after the loop. In the actual tests, the L2 cache will take ~4ms by
default for big cluster.

In the real world that give 10ms for the enough margin, like the
ddr/cpu/cci frequency and other factors that will affect it.
