mmc: sdhci-omap: Set caps2 to indicate no physical write protect pin

After commit 6d5cd068ee59fba ("mmc: sdhci: use WP GPIO in
sdhci_check_ro()") and commit 39ee32ce486756f ("mmc: sdhci-omap: drop
->get_ro() implementation"), sdhci-omap relied on SDHCI_PRESENT_STATE
to check if the card is read-only, if wp-gpios is not populated
in device tree. However SDHCI_PRESENT_STATE in sdhci-omap does not have
correct read-only state.

sdhci-omap can be used by platforms with both micro SD slot and standard
SD slot with physical write protect pin (using GPIO). Set caps2 to
MMC_CAP2_NO_WRITE_PROTECT based on if wp-gpios property is populated or
not.

This fix is required since existing device-tree node doesn't have
"disable-wp" property and to preserve old-dt compatibility.
