From: Veerabhadrarao Badiganti <vbadigan@xxxxxxxxxxxxxx>
On some sc7180 based platforms where external pull is not present on cd-gpio,
this gpio state is getting read as HIGH when sleep config is applied on it.
This is resulting in SDcard rescan after suspend-resume even though SDcard
is not present.
Update cd-gpio sleep config with bais-pull to fix this issue.
