FIT (Flat Image Tree) allows a ramdisk to be included in each
configuration. Add support for this to the script.
This feature is not available via 'make image.fit' since the ramdisk
likely needs to be built separately anyway, e.g. using modules from
the kernel build. Future work may provide support for doing that.
Note that the uncompressed size is not correct when a ramdisk is used,
since it is too expensive to decompress the ramdisk.

The kernel is likely at least 16MB so we may as well use that as a step

The commit 24ede430fa ("PCI: designware-ep: Add multiple PFs support
for DWC") added support for multiple PFs in the DWC driver, but the
implementation was incomplete. It did not properly support MSI/MSI-X,
as well as BAR and inbound ATU mapping for multiple PFs. The MSI/MSI-X
issue was later fixed by commit 47a062609a ("PCI: designware-ep:
Modify MSI and MSIX CAP way of finding") by introducing a per-PF
struct dw_pcie_ep_func.
However, even with both commits, the multiple PF support in the driver
remains broken because BAR configuration and ATU mappings are managed
globally in struct dw_pcie_ep, meaning all PFs share the same BAR-to-ATU
mapping table. This causes one PF's EPF to overwrite the address
translation of another PF's EPF in the internal ATU region,
creating conflicts when multiple physical functions attempt to
configure their BARs independently.
The commit cfbc98dbf44d ("PCI: dwc: ep: Support BAR subrange inbound
mapping via Address Match Mode iATU") later introduced Address Match
Mode support, which suffers from the same multi-PF conflict issue.
Fix this by moving the required members from struct dw_pcie_ep to
struct dw_pcie_ep_func, similar to what commit 47a062609a
("PCI: designware-ep: Modify MSI and MSIX CAP way of finding") did for
MSI/MSI-X capability support, to allow proper multi-function endpoint
operation, where each PF can configure its BARs and corresponding
internal ATU region without interfering with other PFs.

Some shimmer/colorful points appears when using the steamOS color
pipeline for HDR on gaming with DCN32. These points look like black
values being wrongly mapped to red/blue/green values. It was caused
because the number of hw points in regular LUTs and in a shaper LUT was
treated as the same.
DCN3+ regular LUTs have 257 bases and implicit deltas (i.e. HW
calculates them), but shaper LUT is a special case: it has 256 bases and
256 deltas, as in DCN1-2 regular LUTs, and outputs 14-bit values.
Fix that by setting by decreasing in 1 the number of HW points computed
in the LUT segmentation so that shaper LUT (i.e. fixpoint == true) keeps
the same DCN10 CM logic and regular LUTs go with `hw_points + 1`.

[Why]
DCN 3.6+ hardware supports CRC-32 polynomial in addition to the
legacy CRC-16. Enable 32-bit CRC values per color component for
improvement of precision in display validation.
[How]
When userspace sets crc_poly_mode (0=CRC-16, 1=CRC-32) via the debugfs
interface, the value is stored in dm_irq_params.crc_poly_mode. When CRC
source configuration triggers amdgpu_dm_crtc_configure_crc_source(),
crc_poly_mode is retrieved from dm_irq_params and passed to
dc_stream_configure_crc().
In the DC layer, dc_stream_configure_crc() sets crc_poly_mode into the
crc_params structure and passes it to optc35_configure_crc(). If the
hardware supports the OTG_CRC_POLY_SEL register, the register is
programmed to select CRC-16 or CRC-32 polynomial.
When reading CRC values, optc35_get_crc() checks whether CRC32 register
masks are available. If present, it reads 32-bit CRC values from
OTG_CRC0/1_DATA_R32/G32/B32 registers; otherwise, it falls back
to reading 16-bit CRC values from legacy OTG_CRC0/1_DATA_RG/B
registers.
