soc/mediatek/mt8196: Add SPM loader

This patch adds support for loading SPM firmware from CBFS to SPM SRAM
and fix the SPM register definitions. 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 suspends.

coreboot log:
CBFS: Found 'spm_firmware.pm' @0xadf00 size 0x5a60 in mcache @0xfffdd3c
mtk_init_mcu: Loaded (and reset) spm_firmware.pm in 3 msecs (30080 byt)

TEST=build pass
BUG=348147674
