The CONNECTOR_ID_USBC check was removed to fix a regression, but it was
re-introduced by accident. This commit drops the USBC that causes the

[WHY]
If there are no DC clock limits present, or if the DC limits are the same
as the AC limits, we can disable the AC/DC codepath as there won't be any
validation differences between the two modes.
[HOW]
When all DC power mode clock limits are the same as the max clock
values, there won't be any difference between AC mode and DC mode. Zero
out DC limits that equal max and provide a new cap to indicate the
presence of any non-zero DC mode limit. In summary:
- zero out DC limits that are the same as max clock value
- new dc cap to indicate the presence of DC mode limits
- set limits present if any clock has distinct AC and DC values from SMU

We do not directly enable/disable VCN IRQ in vcn 5.0.0.
And we do not handle the IRQ state as well. So the calls to
disable IRQ and set state are removed. This effectively gets
rid of the warining of

in amdgpu_irq_put().

This commit fixes multiple potential truncations when writing the
strings _pfp.bin, _me.bin, _rlc.bin, and _mec.bin into the fw_name

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.
