drivers: add ufs stack

If UFS device is initialized, we could just make it out of
hibernation by UFS_FLAGS_SKIPINIT. And vendor's dirver is always
focus on PHY setting. We could use UFS driver directly if it
exits from hibernation.

There're eight LUNs in UFS device. The UFS driver only provides
the read/write API with LUN. User could define his own read/write
since user may want to access different LUNs.

Only the compiler is switched to ARM Compiler 6. The assembler and linker
are provided by the GCC toolchain.

ARM Compiler 6 is used to build TF when the base name of the path assigned
to `CC` matches the string 'armclang'.

`CROSS_COMPILE` is still needed and should point to the appropriate
GCC toolchain.

Tested with ARM CC 6.7.

This options enables an implementation of SHA-256 that has a smaller
code footprint (~1.6 KB less) but is also ~30% slower. For ARM
platforms, code size is currently considered more important than
execution speed in the mbed TLS crypto module.

Added a small note about this option to the documentation of the
authentication framework.
