Subject: [Bug fix] octeon-i2c driver improvement [2/2]

Hi Jan and David,

For octeon-i2c driver, there has duplicated interrupt disable in octeon_i2c_isr(),
octeon_i2c_hlc_wait() and octeon_i2c_wait(), since octeon_i2c_hlc_wait() and
octeon_i2c_wait() has pair of interrupt enable and disable, so the interrupt
disable in octeon_i2c_isr() is not necessary. attached patch removed this
unnecessary interrupt disable step.

Please have time to review it. Thanks.
