TF-A: Add HASH_ALG default value to defaults.mk

Browse source 
This patch adds default value of 'sha256' for HASH_ALG
build flag to 'make_helpers\defaults.mk', according to
'docs\getting_started\build-options.rst'.
This fixes Measured Boot driver error when TF-A uses
default HASH_ALG value and TPM_HASH_ALG is set to
sha384 or sha512.
