fix(rdn2): populate TOS_CONFIG only when SPMC_AT_EL3 is enabled

Browse source 
As of now, TOS_FW_CONFIG (trusted OS config) gets populated by default
for RD-N2. However, TOS_FW_CONFIG is required only when SPMC_AT_EL3 is
enabled. As the platform should support SPMC_AT_EL3 disabled mode as
well, populate TOS_CONFIG only when SPMC_AT_EL3 is enabled.
Additionally, building of rdn2_stmm_sel0_manifest.dtb is made
conditional to align with this configuration.
