Igor Opaniuk 2147a16983 dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIO 
Use CONFIG_IS_ENABLED() macro, which provides more convenient
way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs
for both SPL and U-Boot proper.

CONFIG_IS_ENABLED(DM_I2C) expands to:
- 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y',
- 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y',
- 0 otherwise.

All occurences were replaced automatically using these bash cmds:
$ find . -type f -exec sed -i
     's/ifndef CONFIG_DM_I2C/if !CONFIG_IS_ENABLED(DM_I2C)/g' {} +
$ find . -type f -exec sed -i
    's/ifdef CONFIG_DM_I2C/if CONFIG_IS_ENABLED(DM_I2C)/g' {} +
$ find . -type f -exec sed -i
    's/defined(CONFIG_DM_I2C)/CONFIG_IS_ENABLED(DM_I2C)/g' {} +
$ find . -type f -exec sed -i
    's/ifndef CONFIG_DM_I2C_GPIO/if !CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} +
$ find . -type f -exec sed -i
    's/ifdef CONFIG_DM_I2C_GPIO/if CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} +
$ find . -type f -exec sed -i
    's/defined(CONFIG_DM_I2C_GPIO)/CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} +

Overview
--------
QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance
development platform, with a complete debugging environment.
The LS1012ARDB board supports the QorIQ LS1012A processor and is
optimized to support the high-bandwidth DDR3L memory and
a full complement of high-speed SerDes ports.

LS1012A SoC Overview
--------------------
Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc for LS2080A
SoC overview.

LS1012ARDB board Overview
-----------------------
 - SERDES Connections, 4 lanes supporting:
      - PCI Express - 3.0
      - SGMII, SGMII 2.5
      - SATA 3.0
 - DDR Controller
     - 16-bit, 1 GB DDR3L SDRAM memory, running at data rates up to 1 GT/s
 -QSPI: A dual 1:3 switch, NX3L4357GM,115 (U35) drives the QSPI chip-select
 signals to
    - QSPI NOR flash memory (2 virtual banks)
    - the QSPI emulator.s
 - USB 3.0
    - one high-speed USB 2.0/3.0 port.
 - Two enhanced secure digital host controllers:
    - SDHC1 controller can be connected to onboard SDHC connector
    - SDHC2 controller: Three dual 1:4 mux/demux devices,
    74CBTLV3253DS (U30, U31, U33) drive the SDHC2 signals to eMMC,
    SDIO WiFi, SPI, and Ardiuno shield
 - 2 I2C controllers
 - One SATA onboard connectors
 - UART
   - The LS1012A processor consists of two UART controllers,
   out of which only UART1 is used on RDB.
 - ARM JTAG support

Booting Options
