[U-Boot] [PATCH V7 2/3] PMIC: Add dialog pmic support

[Jason Liu <jason.hui@linaro.org>]

This patch add dialog pmic(DA9053) driver with I2C interface support
In order to not duplicate code and according to the discussion on the
mail-list, change fsl_pmic.c to spi_i2c_pmic.c.Actaully,spi_i2c_pmic.c
is just a wrapper for PMIC communication when SPI or I2C is used.

change since v1:
- use one file to support fsl pmic and dialog pmic
- rename fsl_pmic.c to spi_i2c_pmic.c
