intel/fsp_baytrail/i2c: mask i2c interrupts in i2c_init()
i2c_init() leaves the I2C device enabled. Combined with the default interrupt mask (0x8ff) and the fact that the interrupt line is shared, this leads to an interrupt storm in the OS until a proper I2C driver is loaded. This change clears the interrupt mask to prevent the interrupt storm.
