Add ACPI support to 8250_mtk driver. This makes it possible to
use UART on ARM-based desktops with EDK2 UEFI firmware.

This is a resend of the previous version, right?  Or did something
change?

confused,

==> Hi Greg,
Yes, previously Yenchia Chen helped to send out a version. Currently,
this solution is specifically for the GB10 project and was made to
support Windows ACPI settings. 

In actual application scenarios, the apdma clk will not be turned off
in normal mode. It is only turned off in the SSPM microprocessor
after
entering standby, and when resuming, the apdma clk is re-enabled by
SSPM.

As for other Linux projects, apdma still uses the DTS node.

Thanks

Hi Greg,
Do you have other suggestion for this?

Thanks
