IKXCLOCK-2635: i2c: inline the threaded interrupt on single core
The I2C driver uses a threaded interrupt, which results in over 100us
of extra cpu activity. Update the omap i2c driver to not use a
threaded interrupt on single core processors. This reduces the i2c
latency from about 150us to 30us at 1.2GHz.
