This patch moves the davinci i2c_defs.h file to drivers.i2c directory. It will allow to reuse the davinci_i2c driver for TI Keystone2 SOCs.
Not used "git mv" command to move the file because small part of it with definitions specific for Davinci SOCs has to remain in the arch/arm/include/asm/arch-davinci.
