wlcore: add quirk to disable ELP
ELP is a very complicated process in the firmware. Due to its
complexity, in some early firmware revisions, the ELP feature is
disabled. To support this cases, this patch adds a quirk that
disables ELP mode.
When ELP is not supported, do not attempt to enter ELP when requested by
the driver.
