soc/intel/apollolake: Set sdcard card detect (CD) host ownership
Currently sdcard CD host ownership is always owned by the GPIO driver.
Due to this sdcard detection fails during initial boot process and OS
fails to boot from sdcard.
This implements change in host ownership from acpi to GPIO driver when
kernel starts booting.
BUG=b:35648535
TEST=Check OS boot from sdcard.
