[ Upstream commit 8c3e5b74b9e2146f564905e50ca716591c76d4f1 ]
The mmc core takes a specific path to support initializing of a non-standard SDIO card. This is triggered by looking for the card-quirk, MMC_QUIRK_NONSTD_SDIO.
In mmc_sdio_init_card() this gets rather messy, as it causes the code to bail out earlier, compared to the usual path. This leads to that the OCR doesn't get saved properly in card->ocr. Fortunately, only omap_hsmmc has been using the MMC_QUIRK_NONSTD_SDIO and is dealing with the issue, by assigning a hardcoded value (0x80) to card->ocr from an ->init_card() ops.
To make the behaviour consistent, let's instead rely on the core to save the OCR in card->ocr during initialization.
