[PATCH v2 3/3] mmc: sdhci-tegra: drop ->get_ro() implementation

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

The SDHCI core is know properly checking for the state of a WP GPIO,
so there is no longer any need for the sdhci-tegra code to implement
->get_ro() using mmc_gpio_get_ro().

Changes since v1:
 - Added Tested-by/Acked-by from Thierry Reding

Note: this patch has only been compiled tested, as I don't have the
hardware to test it.
