Avoid the array lookup, converting the PLL macros after ICL to
_PICK_EVEN_RANGES. This provides the following reduction in code size:
$ size build64/drivers/gpu/drm/i915/i915.o{.old,.new}
text data bss dec hex filename
4027456 185703 6984 4220143 4064ef build64/drivers/gpu/drm/i915/i915.o.old
4026997 185703 6984 4219684 406324 build64/drivers/gpu/drm/i915/i915.o.new
At the same time it's safer, avoiding out-of-bounds array access. This
allows to remove _MMIO_PLL3() that is now unused.

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 Restructured Text 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.
