With DM enabled, this patch enables DM_SERIAL and removes
the NS16550 initialization from da850_lowlevel since the driver
will take care of that itself.

With the pinctrl function enabled and the device tree setting up
the pins we want to use, this patch removes the manual pinmuxing
except for that which is not done by the device tree and minimal
pins necessary for SPL (like serial, GPMC, and MMC)

With DM_I2C and DM_GPIO working, this patch can enable the

With DM_GPIO and DM_MMC translating GPIO_ACTIVE_LOW, any boards
using the 'cd-invert' option will no longer need to do this. This
patch removes the support for 'invert' from the MMC driver.

This adds the support for PDA detection as common code for
Atmel boards.
Using the one wire interface over GPIO , an EEPROM memory is read
and compared to preprogrammed values for PDA screens TM4300, TM7000
and TM7000B.
Once the PDA is detected, an environment variable is set accordingly.
