[U-Boot] [PATCH v2 04/11] KM: add CONFIG_KM_I2C_ABORT option

[Valentin Longchamp]

This must be defined for all the keymile boards that use the common
i2c_abort function that is used to "reset" the I2C bus. These are
currently km82xx and km_arm boards. This patch defines them for both
architectures.

The kmp204x and km83xx boards use other functions and thus do not define
this.

Changes in v2:
- Introduce CONFIG_KM_I2C_ABORT #define to avoid #if !defined in
  common.c
