mtd: mxc_nand: support i.MX21
On i.MX21 SoCs, if the NFC_CONFIG1:NFC_INT_MASK bit is set,
NFC_CONFIG2:NFC_INT always reads out zero, even if an
operation is completed. 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.
