On Intel Tangier the SDHCI #2 provides SD card connection.
Add GPIO card detection for it.
Fixes: 39665beed6f7 ("x86: tangier: Enable ACPI support for Intel Tangier")
BugLink: https://github.com/edison-fw/meta-intel-edison/issues/135

v3: basically returned to the content of v2 (pull bias back to none)
since there is nothing special about the signal which is supposed
to be triggered by both edges
