sp_min: Avoid platform security reconfiguration

In the case of Juno AArch32, platform security configuration
gets done from both BL2 and SP_MIN(BL32) components when
JUNO_AARCH32_EL3_RUNTIME and RESET_TO_SP_MIN build options
are set.
Fix is provided to avoid Platform security configuration from
SP_MIN when it is already done in BL2.
