The U_BOOT_DRIVER macro creates a list of drivers used at link time, and
all entries here must be unique. This in turn means that all entries in
the code should also be unique in order to not lead to build failures
later with unexpected build combinations. Typically, the problem we have
here is when a driver is obviously based on another driver and didn't
update this particular field and so while the name field reflects
something unique the linker entry itself is not. In a few places this
provides a more suitable string name as well, however.

Prevent the Qualcomm watchdog from autostarting and ensure it's stopped
when the driver probed. In some cases the watchdog is left running by
a previous bootloader stage. Disable autostart so it isn't left running
when we boot into the OS, this behaviour can be changed by enabling
autostart in the board defconfig.

This series adds basic support for Mediatek soc MT8195:
- clock driver
- watchdog
- add a new macro helper to define gate clock. Other driver can be
  cleaned later to use the new macro

Other driver will be added later.

It will also serve as basis for board support such as MT8395_EVK based
on MT8195.

This adds basic support for MediaTek MT8195 SoC.

Add watchdog support by adding upstream compatible string.

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

Added a check to ensure the requested timeout does not exceed the
hardware's maximum supported value. This prevents register overflow
and ensures watchdog reliability.

So, added a check in qcom_wdt_start() to ensure the requested timeout
does not exceed the hardware-supported maximum value. If the requested
value exceeds the maximum value, then the timeout is clamped
at maximum value.

The timeout is first converted to watchdog ticks and then compared
against QCOM_WDT_MAX_TIMEOUT. This helps prevent misconfiguration
and potential watchdog misbehavior due to overflow.

QCOM_WDT_MAX_TIMEOUT is set to 0xFFFFF, as Qualcomm SoCs typically
use 20 bits to store bark/bite timeout values.

This work builds upon the previous submission:
