Now that we have a framework for the SMCCC TRNG interface, and the
existing Juno entropy code has been prepared, add the few remaining bits
to implement this interface for the Juno Trusted Entropy Source.
We retire the existing Juno specific RNG interface, and use the generic
one for the stack canary generation.

plat/arm: juno: Condition Juno entropy source with CRC instructions
The Juno Trusted Entropy Source has a bias, which makes the generated
raw numbers fail a FIPS 140-2 statistic test.
To improve the quality of the numbers, we can use the CPU's CRC
instructions, which do a decent job on conditioning the bits.
This adds a *very* simple version of arm_acle.h, which is typically
provided by the compiler, and contains the CRC instrinsics definitions
we need. We need the original version by using -nostdinc.

plat/arm: juno: Refactor juno_getentropy()
Currently we use the Juno's TRNG hardware entropy source to initialise
the stack canary. The current function allows to fill a buffer of any
size, but we will actually only ever request 16 bytes, as this is what
the hardware implements. Out of this, we only need at most 64 bits for
the canary.
In preparation for the introduction of the SMCCC TRNG interface, we
can simplify this Juno specific interface by making it compatible with
the generic one: We just deliver 64 bits of entropy on each call.
This reduces the complexity of the code. As the raw entropy register
readouts seem to be biased, it makes sense to do some conditioning
inside the juno_getentropy() function already.
Also initialise the TRNG hardware, if not already done.

plat/arm: fvp: Protect GICR frames for fused/unused cores
Currently, BLs are mapping the GIC memory region as read-write
for all cores on boot-up.
This opens up the security hole where the active core can write
the GICR frame of fused/inactive core. To avoid this issue, disable
the GICR frame of all inactive cores as below:
1. After primary CPU boots up, map GICR region of all cores as
read-only.
2. After primary CPU boots up, map its GICR region as read-write
and initialize its redistributor interface.
3. After secondary CPU boots up, map its GICR region as read-write
and initialize its redistributor interface.
4. All unused/fused core's redistributor regions remain read-only and
write attempt to such protected regions results in an exception.
As mentioned above, this patch offers only the GICR memory-mapped
region protection considering there is no facility at the GIC IP
level to avoid writing the redistributor area.
These changes are currently done in BL31 of Arm FVP and guarded under
the flag 'FVP_GICR_REGION_PROTECTION'.
As of now, this patch is tested manually as below:
1. Disable the FVP cores (core 1, 2, 3) with core 0 as an active core.
2. Verify data abort triggered by manually updating the ‘GICR_CTLR’
register of core 1’s(fused) redistributor from core 0(active).

plat/arm: Remove ARM_LINUX_KERNEL_AS_BL33 relying on RESET_TO_BL31
So far the ARM platform Makefile would require that RESET_TO_BL31 is set
when we ask for the ARM_LINUX_KERNEL_AS_BL33 feature.
There is no real technical reason for that, and the one place in the
code where this was needed has been fixed.
Remove the requirement of those two options to be always enabled
together.
This enables the direct kernel boot feature for the Foundation FVP
(as described in the documentation), which requires a BL1/FIP
combination to boot, so cannot use RESET_TO_BL31.

plat/arm: Always allow ARM_LINUX_KERNEL_AS_BL33
At the moment we have the somewhat artifical limitation of
ARM_LINUX_KERNEL_AS_BL33 only being used together with RESET_TO_BL31.
However there does not seem to be a good technical reason for that,
it was probably just to differentate between two different boot flows.
Move the initial register setup for ARM_LINUX_KERNEL_AS_BL33 out of the
RESET_TO_BL31 #ifdef, so that we initialise the registers in any case.
This allows to use a preloaded kernel image when using BL1 and FIP.
