Use ARM architectual timer by initializing frequency to 13 MHz. Since
system timer is the source of the architectual timer, we also call
`timer_prepare` in `init_timer`.

TEST=run `suite:faft_bios` to verify the firmware stability.
check timestamps by cbmem.

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.

- Use common SoC drivers for DRAM calibration support.
- Remove emi.h because sdram_size() is already declared in
common/include/soc/emi.h.
- Add dramc_param.h and dramc_soc.h to prepare for implementation of
DRAM full calibration.

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
