Document address for IPQ8064 Qcom UARTDM Debug LL Kernel config.

APQ8064 and IPQ8064 have pretty much the same register but on IPQ8064
SoC the most common configuration is to provide UART on GSBI4 hence
suggest the usage of GSBI4 PHY Address.

This has been tested on a Netgear R7800 while bisecting some problem
with the ARM decompressor confirming correct output with the Debug LL
configs.
