Originally, when DEVICE_TRNG is defined, MBEDTLS_ENTROPY_HARDWARE_ALT will also be defined
accordingly to provide entropy source. This is fine for targets supporting TRNG. However, for
targets without TRNG, it is also possible to provide non-TRNG entropy source solution via the
define MBEDTLS_ENTROPY_HARDWARE_ALT. Related discussion can be found at:

The DEVICE_FOO macros are always defined (either 0 or 1).
This patch replaces any instances of a define check on a DEVICE_FOO
macro with value test instead.

mbed.h was added in test, via greentea and utest header files. 'mbed.h' is removed
from header files and required header file and namespace is added to CPP/C files
