DLE stands for Double Link Engine that is used to maintain buffer page.
To avoid linking to wrong pages, we check the used page size during
initialization and stop driver probe if the used size is unexpected.
Currently, we check the page size used by PLE (payload engine) and WDE
(WiFi descriptor engine). For coming WiFi 7 chips, additional reserved
size is added for BB as buffer to run LA mode, so add and check the
reserved size as well.
