Lastbus is a bus debug tool. When the bus hangs, the bus transmission
information before resetting will be recorded.
The watchdog cannot clear it and it will be printed out for bus hanging
analysis.
There are two versions for lastbus:
Version 1 for MT8186, and version 2 for MT8188.
BUG=b:263753374
TEST=build pass.

To simplify the calling sequence for mtk_wdt_preinit() and we always
adjust request setting in mtk_wdt_preinit(), we rename
mtk_wdt_preinit() to mtk_wdt_set_req() and call it in mtk_wdt_init().
From this modification, we can also enable thermal hardware reset
feature (CB:64676, CB:64675) in MT8192 and MT8195.

In MT8186, we need to disable spm_thermal to prevent it from
influencing other wdt status.
There are two hardware pathes which are used for asserting watchdog
from thermal. We can disable status of path 1 because status of
path 2 is used.
1. Thermal -> SPM -> WDT
2. Thermal -> WDT
Spm_thermal (path 1) is a flexible option for software control, and
the hardware designer suggests that we should disable it if we don't
use it.

Tracker is a debugging tool, and MT8186 only supports AP tracker.
When bus timeout occurs, the system reboots and latches some values
which could be used for debugging.
This function will be triggered only when it encounters the bug
hanging issue.

GIC (generic interrupt controller) defines architectural requirements
for handling all interrupt sources and common interrupt controller
programming interface.
GIC needs to be pre-initialized on MT8186, so we add this initialize
function.

EINT event mask register is used to mask EINT wakeup source.
All wakeup sources are masked by default. Since most MediaTek SoCs do
not have this design, we can't modify the kernel EINT upstream driver to
solve the issue 'Can't wake using power button (cros_ec) or touchpad'.
So we add a driver here to unmask all wakeup sources.

MT8186 requires writing speical value to mode register to clear
status register. The flow of clear status is different from other
platforms, so we override mtk_wdt_clr_status() for MT8186.

Add new folder and basic drivers for Mediatek SoC 'MT8186'.
Difference of modules including in this patch between MT8186 and existing SoCs:
Timer:
Similar to MT8195, MT8186 uses v2 timer.
EMI/PLL/SPI:
Different from existing SoCs.
TEST=boot from SPI-NOR and show uart log on MT8186 EVB
