Allow PSCI layer to handle any SiP service functions added by platform vendors. PSCI layer will look for SiP service function in the SiP function table located in '._secure_svc_tbl_entries' section if the SMC function identifier is not found in the PSCI standard functions table. Use DECLARE_SECURE_SVC macro to declare and add platform specific SiP service function. This new section '._secure_svc_tbl_entries' is located next to '._secure.text' section. Refer to arch/arm/cpu/armv8/u-boot.lds. Signed-off-by: Chee Hong Ang <chee.hong.ang@intel.com>
