The WFHWSIZE constant defines the maximum size for the hardware-specific waveform representation buffer. It is currently local to drivers/pwm/core.c, which makes it inaccessible to external tools like bindgen. Move the constant to include/linux/pwm.h to make it part of the public API. As part of this change, rename it to PWM_WFHWSIZE to follow standard kernel conventions for namespacing macros in public headers. This allows bindgen to automatically generate a corresponding constant for the Rust PWM abstractions, ensuring the value remains synchronized between the C core and Rust code and preventing future maintenance issues.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
