mb/google/dedede/var/drawcia: Enable LTR mechanism for PCIe root port 8
Realtek AX generation IC utilizes LTR-issued latency requests to
optimize WiFi latency and power consumption, it requires host
enabling LTR to meet the design requirement. We enabled the host's
LTR by enabling PCIe root port 8, which met resltek's technical
requirements.
BUG=b:377400590
TEST=Tested on Drawman with RTL8852BE
Use command $ lspci -vv, LTR+ is listed on DevCtl2
