ASoC: SOF: ipc4-pcm: Fix incorrect comparison with number of tdm_slots
In ipc4_ssp_dai_config_pcm_params_match() when comparing params_channels()
against hw_config->tdm_slots the comparison should be a <= not a ==.

The number of TDM slots must be enough for the number of required channels.
But it can be greater. There are various reason why a I2S/TDM link has more
TDM slots than a particular audio stream needs.

The original comparison would fail on systems that had more TDM slots.

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.
