soc/mediatek/mt8192: add spmfw loader
This patch adds 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.
BUG=b:159079649
TEST=suspend with command `powerd_dbus_suspend` and
wake up the DUT by powerkey
