[PORT FROM R2] nfc: split long i2c xfers into smaller chunks supported by i2c controller

[PORT FROM R2] nfc: split long i2c xfers into smaller chunks supported by i2c controller

BZ: 23876

Due to limitation of I2C silicon on Penwell I2C xfers longer than 31 bytes
are not guaranteed to be atomic. If TX fifo underrun occurs during such
a transfer I2C controller will automatically generate a STOP condition.

This patch splits all long I2C transfer requested by NFC stack into chunks
of up to 31 bytes and transmits them as separate I2C transfers.
