core: mm: fix zero-length access check inconsistency

Fix vm_check_access_rights() so it handles zero-length memory ranges
consistently. Previously, the function had inconsistent behavior for
zero-length checks:
- For page-aligned addresses: Would skip the page checking loop entirely
and return TEE_SUCCESS.
- For unaligned addresses: Would round uaddr down to page boundary and
return a result based on that page.

With this change flags = SECURE | NON_SECURE will still fail to preserve
the sanity checking, but all other zero-length ranges result in
TEE_SUCCESS.

Specifically this was required due to an interaction between OP-TEE and
Rust where Keymint [0] would call the Teaclave [1] wrapper around
TEE_MACComputeFinal with an empty temporary slice (pointer + length
pair) as the final message (&[]). Rust always requires the pointer to be
non-null, but allows it to dangle when length is zero. As a result the
arguments passed to TEE_MACComputeFinal were message=(void *)1,
messageLen=0. These arguments are passed unmodified to
vm_check_access_rights regardless of the length and presumably relied
on the page-aligned case to handle NULL + 0.

Fix AES-GCM in-place decryption to ensure GHASH always uses the original

causing authentication failures. Now GHASH is processed before decryption,
so in-place and non in-place decryption both work correctly without extra

produce correct authentication tags.

I could not identify which change exactly caused the limit to be reached,
and I didn't manage to identify any obvious waste of disk space in the
build. I noticed however that building with RUST_ENABLE=y (the default)
uses approximately 6 GB more than with RUST_ENABLE=n (27 GB vs 21 GB,
that's the size of the whole OP-TEE tree in the end).
The two "nightly" Rust toolchains that are downloaded when optee_rust is
built account for 1.6 GB on their own.

Therefore, and until we find a better solution or GitHub increases the
disk space allocated to CI jobs, disable Rust in the Xen and Xen FF-A
jobs. This allows the Xen jobs to pass again.

drivers: gpio: add configure functions

Align the OP-TEE GPIO driver with GPIO lib (devm_gpiod_get_index with
enum gpiod_flags) and add a way to select the GPIO configuration directly
during request with the new function, gpio_dt_cfg_by_index().

This patch remove assumption on GPIO direction (gpio input was assumed in
GPIO driver) or output level when the GPIO is requested by consumer.
with this patch it must be requested explicitly with:
- GPIO_IN: configure the input GPIO
- GPIO_ASIS: direction is managed by caller later with gpio_set_value()
call.
- GPIO_OUT_LOW / GPIO_OUT_HIGH: output GPIO at expected level,
the sequence for GPIO have the correct order to avoid glitch by using
the gpio function at the correct order.

This patch is a preliminary step for the introduction of ops configure.
The API gpio_dt_get_by_index() is keep for backward compatibility but
should be used with gpio_configure() or replaced by gpio_dt_cfg_by_index().

Now gpio_configure() is only used in the 2 drivers, regulator_fixed and
regulator_gpio, because in these drivers the flags gpio->dt_flags are
modified after call of gpio_dt_get_by_index().

For get_voltage_level_gpio(), GPIO_OUT_HIGH is used by default as it is
done in Linux function of_get_gpio_regulator_config().
