Currently many commands may silently fail without any sign of that.
This patch let this info to be printed once test is running in

For the future it might be useful to fail the test if command has
failed, however it would require a bit of rework inside test

A simple example of silent failure without reporting it would to
add some non-existent HMP command into 'hmp_cmds' list. In this case
test will report it successfully passed without error.

Currently get_phys_addr() and its various subfunctions return
a hard-coded fault status register value for translation
failures. This is awkward because FSR values these days may
be either long-descriptor format or short-descriptor format.
Worse, the right FSR type to use doesn't depend only on the
translation table being walked -- some cases, like fault
info reported to AArch32 EL2 for some kinds of ATS operation,
must be in long-descriptor format even if the translation
table being walked was short format. We can't get those cases
right with our current approach.
Provide fields in the ARMMMUFaultInfo struct which allow
get_phys_addr() to provide sufficient information for a caller to
construct an FSR value themselves, and utility functions which do
this for both long and short format FSR values, as a first step in
switching get_phys_addr() and its children to only returning the
failure cause in the ARMMMUFaultInfo struct.

For M profile, we currently have an mmu index MNegPri for
"requested execution priority negative". This fails to
distinguish "requested execution priority negative, privileged"
from "requested execution priority negative, usermode", but
the two can return different results for MPU lookups. Fix this
by splitting MNegPri into MNegPriPriv and MNegPriUser, and
similarly for the Secure equivalent MSNegPri.
This takes us from 6 M profile MMU modes to 8, which means
we need to bump NB_MMU_MODES; this is OK since the point
where we are forced to reduce TLB sizes is 9 MMU modes.
(It would in theory be possible to stick with 6 MMU indexes:
{mpu-disabled,user,privileged} x {secure,nonsecure} since
in the MPU-disabled case the result of an MPU lookup is
always the same for both user and privileged code. However
we would then need to rework the TB flags handling to put
user/priv into the TB flags separately from the mmuidx.
Adding an extra couple of mmu indexes is simpler.)

Update striping functionality to be big-endian bit order (as according to
the Zynq-7000 Technical Reference Manual). Output thereafter the even bits
into the flash memory connected to the lower QSPI bus and the odd bits into
the flash memory connected to the upper QSPI bus.

Move the FlashCMD enum, XilinxQSPIPS and XilinxSPIPSClass structures to the
header for consistency (struct XilinxSPIPS is found there). Also move out
a define and remove two double included headers (while touching the code).
Finally, add 4 byte address commands to the FlashCMD enum.
