feat(mediatek): support coreboot BL31 loading
The ChromeOS project uses Coreboot as BL2 instead of MediaTek regular
bootloader, so we use COREBOOT flag to support Coreboot boot flow.

feat(mediatek): implement generic platform port
Implement mandatory platform port functions. Receive
boot arguments from bl2, populate bl33 and bl32 image
entry structs, call each MTK initcall levels
in these mandatory platform port functions.
After bl31_main exit and handover to 2nd boot loader,
mtk bl33 issues SMC and traps to TF-A to execute boot_to_kernel
and then handover to Linux kernel.

refactor(mediatek): smc registration services
To modularize SMC handler, provide macro function in mtk_sip_svc.h.
Drivers register SMC name with value in mtk_sip_def.h, and bind the SMC
handler with the SMC ID by calling DECLARE_SMC_HANDLER macro.
MTK_SIP_SMC_FROM_BL33_TABLE expand the SMC table as switch-case table
statically. DECLARE_SMC_HANDLER wrap SMC handlers with a structure and
put in a section.
During cold boot initialization, in MTK_EARLY_PLAT_INIT level parse the
section to assign each handler with an index. Each SMC request can be
identified with switch-case and take the index to call into
corresponding SMC handler.

During BL31 setup time, we traverse the list to process
each parameter.
