[ Upstream commit2b660ee10a] In vendor driver, size of group cal and dpd cal for mt7981 includes 6G although the chip doesn't support it. mt76 doesn't take this into account which results in reading from the incorrect offset. For devices with precal, this would lead to lower bitrate. Fix this by aligning groupcal size with vendor driver and switch to freq_list_v2 in mt7915_dpd_freq_idx in order to get the correct offset. Below are iwinfo of the test device with two clients connected (iPhone 16, Intel AX210).

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.
