This commit solves issue related to i2c driver performance.
With this commit delay in read write when using i2c timing
algorithm is solved. Used flag mechanism which will check
tim reg value and hz passed.

This commit solves excess usage of RAM. User can now enable/disable
I2C timing algorithm. Disabling of I2C timing algorithm would
reduce RAM usage.

This commit adds I2C timing value automatic calculation algorithm
for all supported families added. This patch improves I2C timing calculation
according to I2C input clock and I2C bus speed.
This commit also allows user to change the system clock and I2C input clock.
