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 level
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.

feat(mediatek): introduce mtk init framework
Provide six initcall levels for drivers/modules initialize HW
controllers or runtime arguments during cold boot.

feat(mediatek): introduce mtk init framework
Provide six initcall levels for drivers/modules initialize HW
controllers or runtime arguments during cold boot.
The initcall level cold boot execution order:
-MTK_EARLY_PLAT_INIT
Call before MMU enabled.
-MTK_ARCH_INIT
MMU Enabled, arch related init(GiC init, interrupt type registration).
-MTK_PLAT_SETUP_0_INIT
MTK driver init level 0.
-MTK_PLAT_SETUP_1_INIT
MTK driver init level 1.
-MTK_PLAT_RUNTIME_INIT
MTK driver init. After this initcall, TF-A handovers to MTK 2nd
bootloader.
-MTK_PLAT_BL33_DEFER_INIT
MTK 2nd bootloader traps to TF-A before handover to rich OS.
This initcall executed in the trap handler(boot_to_kernel).
