soc/mediatek/mt8188: Add SPM loader and initialize SPM in RAM stage
Add support for loading SPM firmware from CBFS to SPM SRAM. SPM needs
its own firmware to enable SPM suspend/resume function which turns off
several resources such as DRAM/mainpll/26M clk when linux system
suspend.
SPM is an essential component on MediaTek SoC, so we initialize PPM
in soc_init(). For MT8188, SPM will handshake with DPM to do
initialization, so we need to call spm_init() after dpm_init().
This SPM flow adds 33ms to the boot time.
firmware log:
mtk_init_mcu: Loaded (and reset) spm_firmware.bin in 25 msecs
SPM: spm_init done in 33 msecs, spm pc = 0x400
TEST=spm pc is 0x400 which is in idle state.
