Subject: [PATCH 2/2] i2c: ocores: respect adapter timeout in IRQ mode

While the timeout field of the i2c_adapter defaults to 1s, it can be
changed, for example using the I2C_TIMEOUT ioctl. Change the ocores
driver to use this timeout instead of hardcoding 1s, also making it
consistent with polling mode.
