drivers: stm32_i2c: fallback to interrupt access when no bottom half

Change stm32_i2c driver to allow I2C transfers in interrupt context
before bottom half thread is initialized and after it's released.

This can be needed by PMIC driver to handle PMCI interrupt events
when bottom half thread is not supported by normal wold.
In that case, PMIC driver would need to register its interrupt to
stm32_i2c driver.

Thread accesses to the bus still start by locking the I2C bus mutex.
Before using the bus, the sequence now masks the PMIC interrupt and
polls (with timeout) on I2C bus access atomic lock. This lock
may be held by an I2C transfer currently executing in an interrupt
context. A 100ms timeout is short enough to also allow
debug console traces in the interrupt sequence. Masking the interrupt
before polling the lock ensures no new pending interrupt will interrupt
us (and execute a I2C transfer) while the thread context accesses the
I2C bus.

Interrupt accesses to the bus atomically set/clear the I2C bus access
lock while executing the interrupt sequence.

core: support dynamic protected memory lending

With CFG_CORE_DYN_PROTMEM=y support dynamic protected memory lending.

A new internal struct mobj_ffa_rsm is added to handle dynamic protected
memory for FF-A.

A new internal struct mobj_protmem is add to handle dynamic protected
memory without FF-A.

Lending non-secure memory to OP-TEE to use it as protected memory means
that it should to become inaccessible by the normal world as part of the
process. This part is currently not supported, since it must be done in
a platform specific way for platforms that support that. QEMU don't
support that.

Adding two platform specific functions, plat_get_protmem_config() and
plat_set_protmem_range() for dynamic protected memory. The functions has
__weak implementation to allow easier testing. However,
plat_set_protmem_range() requires CFG_INSECURE=y since it doesn't change
memory protection.

OPTEE_MSG_CMD_GET_PROTMEM_CONFIG tells the minimal size and required
alignment of protected memory to lend.

For the SMC ABI, OPTEE_MSG_CMD_LEND_PROTMEM lends protected memory
and OPTEE_MSG_CMD_RECLAIM_PROTMEM returns the memory to normal world use.

For the FF-A ABI, FFA_LEND framework request followed by
OPTEE_MSG_CMD_ASSIGN_PROTMEM lends protected memory and
OPTEE_FFA_RELEASE_PROTMEM followed by the FFA_RECLAIM framework
request returns the memory to normal world use.

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().
