Miguel Ojeda db2e7bcee1 drm: nova-drm: fix 32-bit arm build
In 32-bit arm, the build fails with:

    error[E0308]: mismatched types

    help: you can convert a `u32` to a `u64`

    42 |         getparam.set_value(value.into());
       |                                 +++++++

The reason is that `Getparam::set_value` takes a `u64` (from the UAPI),
but `pci::Device::resource_len()` returns a `resource_size_t`, which is a
`phys_addr_t`, which may be 32- or 64-bit.

Thus add an `into()` call to support the 32-bit case, while allowing the
Clippy lint that complains in the 64-bit case where the type is the same.
