This is a direct port of the Linux code as the licence allows it, so
style(9) isn't respected to allow applying directly the upstream commits.
Do not add it to linuxkpi directly but add a new linuxkpi_hdmi module
that drm modules will require later, no need to bloat linuxkpi more.

This required non-trivial changes to `linux_seq_file.c` to manage a new
`(struct seq_file)->size` field. This field is read directly by DRM
drivers, so we can't alias it to a call to sbuf_len(9).
`single_open_size()` also depended on the ability to allocate the sbuf
with a specified size instead of relying on `sbuf_new_auto()`.

DRM drivers set some pointers to `ZERO_SIZE_PTR` directly (without
allocating anything), to treat pointers which were "initialized" (set to
`ZERO_SIZE_PTR`) with no memory allocation like really allocated
pointers. NULL isn't used because it represents a third state.

amdgpu's virtual display feature uses pci_name() to match a module parameter
string, and the documentation shows an example of `0000:26:00.0` for the name.
In our case the name was just `drmn`, which is not actually unique across
devices.
The other consumers are wireless drivers, which will benefit from this
change.
Generate the expected string for pci_name() to return.
