DFD (Design for Debug) is a debugging tool, which scans flip-flops
and dumps to internal RAM on the WDT reset. After system reboots,
those values can be shown for debugging using MTK internal parsing
tools.

This replaces 'SPDX-License-Identifier' tags in all the files under
soc/mediatek/mt8188 for better code re-use in other open source
software stack.
These files were originally from MediaTek and follow coreboot's main
license: "GPL-2.0-only". Now MediaTek replaces these files to
"GPL-2.0-only OR MIT" license.

SSPM is "Secure System Power Manager" that provides power control in
secure domain. The initialization flow is to load SSPM firmware to
its SRAM space and then enable.
It takes 21 ms to load sspm.bin.
coreboot logs:
CBFS: Found 'sspm.bin' @0x21680 size 0xa815 in mcache @0xffffeac4
mtk_init_mcu: Loaded (and reset) sspm.bin in 21 msecs (137348 bytes)
TEST=we can see the sspm logs.

- Turn off L2C SRAM and reconfigure as L2 cache:
Mediatek SoC uses part of the L2 cache as SRAM before DRAM is ready.
After DRAM is ready, we should invoke disable_l2c_sram to reconfigure
the L2C SRAM as L2 cache.
- Configure DMA buffer in DRAM:
Set DRAM DMA to be non-cacheable to load blob correctly.

Add new folder and basic drivers for Mediatek SoC 'MT8188'.
Difference of modules including in this patch between MT8188 and
existing SoCs:
Timer:
Similar to MT8195 and MT8186, MT8188 uses v2 timer.
EMI/PLL/SPI:
Different from existing SoCs.
The implementation is based on these files:
MT8188G_Application Processor Technical Brief_v0.4.pdf
MT8188G_Functional Specification v0.4.pdf
MT8188 Application Processor Registers-1.pdf
MT8188 Application Processor Registers-2.pdf
TEST=saw the coreboot uart log to bootblock
