Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes many meson drivers which, although they did not produce
a warning with the x86 allmodconfig configuration, may cause this
warning with ARM or ARM64 configurations.

Corrections to these descriptions are welcomed. I'm not an expert in
this code so in most cases I've taken these descriptions directly from
code comments, Kconfig descriptions, or git logs.  History has shown
that in some cases these are originally wrong due to cut-n-paste
errors, and in other cases the drivers have evolved such that the
original information is no longer accurate.

Also let me know if any changes need to be split into a separate patch
to go through a separate maintainer tree.
