Changes in v4:
* Renamed the trait from DeviceSize to SizeConstants.
* Added backticks and trailing periods to all hex-value doc comments
on the SZ_* constants.
* Removed redundant type annotations from doc-test examples.
* Used a `use` import for PAGE_SIZE in the module-level doc-test
instead of a fully qualified path.
* Rewrote doc-test comments to clarify the distinction between
module-level constants (no type qualifier) and trait associated
constants (type qualifier required).
* Added Reviewed-by from Eliot Courtney.
Changes in v3:
* Dropped the Alignment::from_u64() patch.
* Reworked define_sizes! macro to accept target types as arguments
(define_sizes!(u32, u64, usize)) using recursive macro arms,
instead of hardcoding impls for u32 and u64. Overflow checking
uses u128 casts so the same assert works for any ("reasonable")
target type.
* Added usize to the DeviceSize implementations, so the trait
covers u32, u64, and usize.
* Hex values for each constant are now proper doc-comments
(forwarded via macro meta), instead of inline comments.
* Rebased onto latest drm-rust-next.
Changes in v2:
* Replaced flat SZ_*_U64 constants with a DeviceSize trait that
provides SZ_* as associated constants on u32 and u64.
* A define_sizes! macro generates everything from one list of names.
* Added Alignment::from_u64() so alignment values can be constructed
from DeviceSize constants without falling back to usize variants.
* Rebased onto drm-rust-next. No longer depends on the Blackwell
patchset.
