Enable TLS hardware acceleration on cypress board

[pan-]

TLS hardware acceleration has been disabled for Cypress board. It should be enabled and initialization of TLS acceleration hardware should be handled when CHIP is initialized.

It seems that TLS hardware acceleration is already enabled. MXCRYPTO_02 is set in MBED_TARGET_LABELS and TARGET_MXCRYPTO_02 in MBED_TARGET_DEFINITIONS. This means that we use the MX_CRYPTO module with cy_hw_crypto functions.
