1. In the Device Tree, merge the PCIe I/O and memory address
windows.The AMD GPU requires a large, contiguous BAR space,
which the previous separate windows could not satisfy.
2. Add a hack to correct the BAR space size calculation. The K1-X platform
reserves a total of 384MB (0x18000000) for PCIe devices (including BAR
and config space). However, the Linux kernel's allocation logic,
influenced by 128MB alignment, attempts to request a full 384MB BAR space
for the GPU.This commit reduces the requested size to 0x16000000,
ensuring the allocation succeeds, as the GPU itself only requires 258MB.
