A SoC like the i.MX6 supports more then one i2c bus. In oder to be
able to use the eeprom command add a new define to specify the
i2c bus to use. If CONFIG_SYS_I2C_EEPROM_BUS is not defined there
is no functional change, else a call to i2c_set_bus_num(..) is
done before calling i2c_read(..) and i2c_write(..).

The self-bias circuit is used by the bandgap during startup.
Once the bandgap has stabilized, the self-bias circuit should
be disabled for best noise performance of analog blocks.
Also this bit should be disabled before the chip enters STOP mode or
when ever the regular bandgap is disabled.

This patch is to implement pmic_mode_init function, and add prototype
in header file.
This function is to set switching mode for pmic buck regulators to
improve system efficiency.
Mode:
OFF: The regulator is switched off and the output voltage is discharged.
PFM: In this mode, the regulator is always in PFM mode, which
is useful at light loads for optimized efficiency.
PWM: In this mode, the regulator is always in PWM mode operation
regardless of load conditions.
APS: In this mode, the regulator moves automatically between
pulse skipping mode and PWM mode depending on load conditions.

lcd_logo() currently performs tasks well beyond just displaying the logo.
It has code which displays splash image, it has logic which determines
when the different display features are displayed, and it is coupled with
the lcd console because it holds the responsibility of returning the
lcd console base address.
Make lcd_logo() just about the logo by:
* Moving splash image display code into a dedicated function
* Moving the logic regarding when various features are displayed to
lcd_clear() (which is arguably not the correct name for housing such
code either, but it is currently the most fitting location code wise)
* Move the responsibility of setting the console base address to
lcd_clear() too.

Reduce the bitmap_plot #ifdef complexity by extracting MPC823-specific code for
setting cmap into its own implementation of lcd_logo_set_cmap(), implemented in
mpc8xx_lcd.c. In the MPC823 implementation, ARRAY_SIZE(bmp_logo_palette) is
switched for BMP_LOGO_COLORS to avoid having to include bmp_logo_data.h, which
would cause a compilation error because the logo data and palette arrays would
be defined twice.
This is a step towards cleaning bitmap_plot() of platform-specific code.

Currently by running the following test:
=> setenv bootcmd reset
=> save
=> reset
, we observe a hang after approximately 20-30 minutes of stress reboot test.
Investigation of this issue revealed that when a single DDR chip select is used,
the hang does not happen. It only happens when the two chip selects are active.
MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence":
"The controller must keep the memory lines quiet (except for CK) for the ZQ
calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256
for other ZQCL and 64 for ZQCS)."
According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL:
"Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines.
Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)"
So make sure to activate one chip select at time (CS0 first and then CS1 later),
so that the required JEDEC delay is respected for each chip select.
With this change applied the board has gone through three days of reboot stress
test without any hang.
