with PMU_PERILP_PD_EN bit enable, the soc will shutdown
cm0, crypto, dcf, imem(normal SRAM), dmac, bootrom, efuse_con,
spi, i2c, uart, saradc, tsadc when suspend, we have M0 code
need to run when suspend in normal SRAM, so we need to take
care of that.

Maybe the coreboot will reference the BL31 parameters (e.g the TZRAM_BASE
and TZRAM_SIZE for DDR secure regions), we can split them and don't have
to hardcode the range in two places.

We used dcf do ddr frequency scaling, but we just include a dcf
binary, it hard to maintain later, we have M0 compile flow in ATF,
and M0 can also work for ddr frequency scaling, so let's use it.
