There are some meson version checks in the code that can be removed as
part of this change:

$ git grep meson.version
drivers/meson.build:    if meson.version().version_compare('>=0.47')
kernel/linux/meson.build:       if meson.version().version_compare('>=0.44')
kernel/linux/meson.build:               if meson.version().version_compare('>=0.44')
meson.build:    meson_version: '>= 0.41'
meson.build:if meson.version().version_compare('>=0.47')
