This function doesn't return and its callers that don't return either
rely on this. Drop the dead attribute and add a panic() after it to make
this expectation explicit. Calling `wfi` in the powerdown sequence is
terminal so even if the function was made to return, there would be no
functional change.
This is useful for a following patch that makes psci_power_down_wfi()
return.

Some of our specialized sections are not prefixed with the conventional
period. The compiler uses input section names to derive certain other
section names (e.g. `.rela.text`, `.relacpu_ops`), and these can be
difficult to select in linker scripts when there is a lack of a
delimiter.
This change introduces the period prefix to all specialized section
names.
BREAKING-CHANGE: All input and output linker section names have been
prefixed with the period character, e.g. `cpu_ops` -> `.cpu_ops`.

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).
