tzc400: add API functions to get firewall configuration

This change modified TZC400 driver to export functions for a platform
to get memory region configuration.

On platform running OP-TEE from a secure DRAM protected from a TZC400
device, OP-TEE Core cannot reconfigure TZC400 for the region is executes
into. The new driver API functions allows such platform at least to
check that TZC400 configuration matches the configuration Core is
statically built with.

drivers: stm32_i2c: allow any bus frequency

Do not limit I2C bus to 3 frequencies (100KHz, 400KHz, 1MHz). Instead
allow for any frequency up to 1MHz. Depending on the requested frequency
defined in clock-frequency DT entry, use the I2C spec data from either
Standard, Fast or Fast Plus mode.

This change removes use of rate IDs and use instead the rate value
itself as identifiers, allowing more flexible implementation.

Changes local variable clock_src in i2c_setup_timing() from uint32_t
to unsigned long for consistency.

core: rename KEEP_INIT() and KEEP_PAGER()

The KEEP_INIT() and KEEP_PAGER() macros are quite often used in C files
immediately after the definition of a function or a structure without a
blank line in between. This style mimics what the Linux kernel does for
a similar use cases: EXPORT_SYMBOL().

Unfortunately, the checkpatch.pl tool expects a blank line after
structure and function definitions, except for a few special cases such
as EXPORT_SYMBOL(). As a result we often get unwanted warnings when we
use KEEP_INIT() and KEEP_PAGER(). Among the exceptions are all words
starting with DECLARE_ or DEFINE_, so by renaming our macros we could
avoid the checkpatch warnings.

This commit renames KEEP_INIT() and KEEP_PAGER() to DECLARE_KEEP_INIT()
and DECLARE_KEEP_PAGER(), respectively. The assembler macros are also
renamed for consistency. No functional change is expected.
