i2c-qup: improve the bus recovery procedure in qup i2c driver

Bus recovery procedure is required when bus goes in a bad state.
Recovery procedure may not get success in single iteration. This
patch increases iteration number to let the bus recover based on
the QUP_I2C_STATUS and QUP_I2C_MASTER_BUS_CLR register values.
