On few sc7180 based boards where external pull up is missing on cd-gpio,
we had seen issues like un-intended interrupt on cd-gpio pin (since its
getting toggled) during runtime PM cycle and resulting in unnecessary
scheduling of SDcard scan (mmc_rescan). This issue is seen only when SDcard
is not present.
By enabling internal pull all the time (bais-pull-up), we can avoid such
issue.
