DT kernel on da850-evm comes up with garbled UART logs. This is because
of mismatch in actual module clock rate and rate specified(clock-frequency)
in DT blob. kernel should not assume or depend on bootloaders clock
configuration, instead let it find the clock rate at runtime.
Issue discussed here before arriving on this implementation:
"ARM: davinci: da850 evm: update clock rate for UART 1/2 DT nodes"

pins
function-mask DT property is now a mask for a pin at each pin offset
inside a given pincontrol register. Fix DA850 DT data to reflect
this change.

Replace /include/ by #include for da850 device tree files, in order to
use the C pre-processor, making use of #define features possible.

Add DT entry for MMC. Also add entry for pinmux information.
Tested:
1) Without GPIO card detection and EDMA support as DT support for
GPIO and EDMA are yet come.
2) By creating/deleting files and mounting/unmounting the partition.

Add I2C0 device tree and pin muxing information to da850-evm.
Also, add OF_DEV_AUXDATA for I2C0 controller driver in da850
board dt file to use I2C0 clock.
Verified i2c0 node gets created in sys class interface as
"/sys/class/i2c-dev/i2c-0/subsystem/i2c-0".
nsekhar@ti.com: tested using i2cdetect and i2cdump.

This patch moves 'interrupt-parent' property to soc node, so that
the child inherits this property. This avoids adding 'interrupt-parent'
property to each node.

For DT, DaVinci platform can use pinctrl-single driver for handling
padconf registers.
Enable PINCTRL Kconfig for MACH_DA8XX_DT platform. Add required
pinctrl DT entries in da850 dts file.
Test procedure
1)Populate DT file with NAND node information.
2)Populate board DT file with pinmux information for NAND.
3)Boot and confirm NAND is detected by the kernel.
4)cat /proc/mtd to show partitions.
