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.

core: upgrade from write32() to io_write32() and friends

Replace use of readX() and writeX() with io_readX() and io_writeX().
The former function are about to be deprecated in favor to the later.

This change upgrades core generic code and drivers.
At some place, io_clrbitsX(), io_setbitsX() and io_clrsetbitsX()
replace the writeX(readX() ...) operations when obvious.
