fix(rdaspen): enable CPU feature runtime checking

Enable runtime feature detection for FEAT_AMU, FEAT_ECV, FEAT_FGT,
and FEAT_MTE2

These features were previously unconditionally enabled (=1) in the build
configuration, causing TF-A to initialize their contexts regardless of
actual CPU support in emulation implementations.

Set them to "2" to enable runtime feature detection instead.

With this change, TF-A checks the ID registers before accessing related
system registers or programming SCR_EL3 bits, avoiding register accesses
on CPUs that lack these features. This primarily addresses issues seen
in emulation environments with incomplete feature support.

fix(rdaspen): fix timer bus cells & fix ranges

The timer node is a child bus that should expose frames via a
translating address space per the timer-with-frames binding.
The #size-cells were updated to <1> from <2>, due to a
validation warning when running dt_validate:

/home/root/fdt/fdt: timer@1a810000: #size-cells: 1 was expected

Updating the cell-size to 1 fixes it, and another fix is also
applied to avoid an empty range property.

This models the timer as a proper translating bus:
- Remove clock-frequency since it is already configured in firmware.
- Update #address-cells from <2> to <1>/
- Update #size-cells from <2> to <1>.
- Provide a non-empty ranges mapping the child space at
0x1a810000 over a 0x30000 window.
- Convert frame and reg values to offsets within the child space.

This removes the dtc warnings in dt_validate and aligns with the
dt-schema expectation for the timer-with-frames layout used by
ACS DT validation.

Improperly configuring cpu features (ENABLE_FEAT_XYZ) can lead to broken

Since the original model, we've gained FEATURE_DETECTION which is meant
to help get platforms configured correctly.

This was introduced in

That patch reduced cpu-ops.mk to an elaborate defaults.mk and moved it
before platform.mk was evaluated. However, that patch missed the
ERRATA_SPECULATIVE_AT setting which must happen after platform.mk,
otherwise its value will not reflect errata state. So put it in the main
Makefile with other similar flag settings after platform.mk.

the FIP itself.
