ta: pas: Add Qualcomm PAS TA
Certificate chain validation requires substantial parsing, which is not
suitable for the constrained S-EL1 environment. While signature
verification is supported by the crypto API, extending the TEE core/PTA
to handle full chain parsing would increase complexity and TCB size.
Move certificate validation to a user TA, keeping the PTA for platform
operations (PAS control, firmware loading, resets). This allows reuse of
existing parsing libraries and keeps the core minimal.

pta: qcom: pas: map PAS resources on demand
Stop registering PAS-related IO regions at platform initialization
time and instead map them on demand when the PAS PTA is initialized.
The WPSS, TURING, LPASS and IRIS regions were previously mapped
statically via register_phys_mem(). These mappings are now removed
and the PAS controller region is mapped dynamically using
core_mmu_add_mapping() when the PTA performs the memory setup.
Since PAS resources are now mapped late, increase
CFG_RESERVED_VASPACE_SIZE to ensure sufficient virtual address
space is available.
This change reduces permanent IO mappings and keeps PAS resources
localized to the PTA implementation.

Add Peripheral Authentication Service (PAS) support for the
Venus video codec, enabling firmware loading through the
existing remoteproc integration.
Firmware authentication is not implemented at this stage.
Execution has been validated by running concurrent video
encode and decode workloads using a GStreamer pipeline.

plat: qcom: kodiak: separate DSP boot logic from PAS resources
The current q6dsp implementation mixes DSP boot sequencing, PAS
resource handling and platform specific register definitions.
Split these responsibilities to simplify the implementation and
allow reuse across platforms:
- move DSP boot sequencing into dsp.c
- move PAS resource handling into pas.c
- introduce Kodiak specific register definitions under
platform/kodiak/
This removes platform details from the generic DSP code and makes the
boot sequence reusable for additional DSP firmwares.

IOMMU/SMMU configuration for co-processors in managed by Linux kernel
running in EL2 on Qualcomm platforms. So add support for returning the
device IO regions needed by WPSS co-processor to access such that
corresponding IOMMU configuration can be performed by the Linux kernel
in EL2.
