[Why]
Underflow occurs when running Netflix in a 4k144 eDP + 4k60 HDMI FRL
setup. It is caused by latency varying based on the DCFCLK/FCLK state.
[How]
Enable urgent latency adjustment and match the reference to existing
ASIC that also see increased latency at low FCLK.

This commit fixes multiple potential truncations when writing the
strings _pfp.bin, _me.bin, _rlc.bin, and _mec.bin into the fw_name
buffer in the gfx_v12_0_init_microcode function in the gfx_v12_0.c file
The ucode_prefix size was reduced from 30 to 15 to ensure the snprintf
function does not exceed the size of the fw_name buffer.
Thus fixing the below with gcc W=1:

We don't get the right offset in that case. The GPU has
an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.

Small APUs(i.e., consumer, embedded products) usually have a small
carveout device memory which can't satisfy most compute workloads
memory allocation requirements.
We can't even run a Basic MNIST Example with a default 512MB carveout.
https://github.com/pytorch/examples/tree/main/mnist. Error Log:
"torch.cuda.OutOfMemoryError: HIP out of memory. Tried to allocate
84.00 MiB. GPU 0 has a total capacity of 512.00 MiB of which 0 bytes
is free. Of the allocated memory 103.83 MiB is allocated by PyTorch,
and 22.17 MiB is reserved by PyTorch but unallocated"
Though we can change BIOS settings to enlarge carveout size,
which is inflexible and may bring complaint. On the other hand,
the memory resource can't be effectively used between host and device.
The solution is MI300A approach, i.e., let VRAM allocations go to GTT.
Then device and host can flexibly and effectively share memory resource.
