feat(ti): set snoop-delayed exclusive handling on A72 cores

Snoop requests should not be responded to during atomic operations. This
can be handled by the interconnect using its global monitor or by the
core's SCU delaying to check for the corresponding atomic monitor state.

TI SoCs take the second approach. Set the snoop-delayed exclusive handling
bit to inform the core it needs to delay responses to perform this check.

As J784s4 is currently the only SoC with multiple A72 clusters, limit
this delay to only that device.

refactor(context-mgmt): move FEAT_HCX save/restore into C

At the moment we save and restore the HCRX_EL2 register in assembly, and
just depend on the build time flags.
To allow runtime checking, and to avoid too much code in assembly, move
that over to C, and use the new combined build/runtime feature check.

This also allows to drop the assert, since this should now be covered by
the different FEAT_STATE_x options.

refactor(context-mgmt): move FEAT_FGT save/restore code into C

At the moment we do the EL2 context save/restore sequence in assembly,
where it is just guarded by #ifdef statement for the build time flags.
This does not cover the FEAT_STATE_CHECK case, where we need to check
for the runtime availability of a feature.

To simplify this extension, and to avoid writing too much code in
assembly, move that sequence into C: it is called from C context
anyways.

This protects the C code with the new version of the is_xxx_present()
check, which combines both build time and runtime check, as necessary,
and allows the compiler to optimise the calls aways, if we don't need
them.

feat: pass SMCCCv1.3 SVE hint bit to dispatchers

SMCCCv1.3 introduces the SVE hint bit added to the SMC FID (bit 16)
denoting that the world issuing an SMC doesn't expect the callee to
preserve the SVE state (FFR, predicates, Zn vector bits greater than
127). Update the generic SMC handler to copy the SVE hint bit state
to SMC flags and mask out the bit by default for the services called
by the standard dispatcher. It is permitted by the SMCCC standard to
ignore the bit as long as the SVE state is preserved. In any case a
callee must preserve the NEON state (FPCR/FPSR, Vn 128b vectors)
whichever the SVE hint bit state.

CORE_PWRDN_EN. This allows the cpu to retry the power down and prevents
the deadlock. TF-A never clears this bit even if it wakes up from the

power down after and the bit is cleared on reset.
