This patch uses enable_irq and disable_irq_nosync instead of NFC_CONFIG1:NFC_INT_MASK to mask NFC interrupts. This allows NFC_CONFIG2:NFC_INT to also be used to detect operation completion on i.MX21. The i.MX21 NFC does not signal reset completion using NFC_CONFIG1:NFC_INT_MASK, so instead reset completion is tested by checking if NFC_CONFIG2 becomes 0.

One way to prevent this is to only allow 1-bit transfers. Another way is playing tricks with the DMA engine, but this isn't mainline yet. So for now, we live with the performance drawback of 1-bit transfers until a nicer solution is found. This patch introduces a new host controller callback 'init_card' which is for now only called from mmc_sdio_init_card().

In case of PIO-transfer it does not clear SDHC-status bit#11/12 in the INT-handler anymore. INT-handler might be called during an ongoing PIO-data-transfer (with some other INT-flag set) and PIO-transfer depends on these bits being set to detect the end of the data-transfer. This also means that at the end of PIO- transfer that PIO-software has to clear these bits itself. However in case of DMA-transfer these bits have to be cleared in the INT-handler, because they are used to generate INTs then. Works solid, no more problems here, can transfer big files.

The driver needs to be aware on which SoC it is running, so the actual device id is being changed in cpu init code. S3C64xx SoCs have 2 OneNAND controllers while S5PC100 and S5PC110 has only one.
