On chiliSOM TPS65217 nWAKEUP pin is connected to AM335x internal RTC
EXT_WAKEUP input. In RTC-only state TPS65217 is notifying about power on
events (such as power buton presses) by setting nWAKEUP output
low. After that it waits 5s for proper device boot. Currently it doesn't
happen, as the processor doesn't listen for such events. Consequently
TPS65217 changes state from SLEEP (RTC-only state) to OFF.
Enable EXT_WAKEUP input of AM335x's RTC, so the processor can properly
detect power on events and recover immediately from RTC-only states,
without powering off RTC and losing time.

ChiliSOM has TPS65217's PWR_EN pin connected to AM335x PMIC_POWER_EN
pin. Processor's PMIC_POWER_EN is controlled by it's internal RTC, hence
RTC subsystem is responsible for proper board poweroff sequence.
This change enables complete poweroff sequence for ChiliBoard, switching
PMIC's state from ACTIVE to SLEEP.

ChiliSOM has 2 Ethernet subsystems with different types of possibly used
PHY interfaces (i.e. MII, RMII, GMII, RGMII). Current code configured
pinmux for RMII on 1st Ethernet subsystem and enabled Ethernet MAC with
1 slave for all boards which use ChiliSOM.
This change moves pinmux configuration of 1st Ethernet subsystem to
ChiliBoard description, as this is board-specific.

uart0 configuration code has been in SOM. However, it is possible to
use all (or none) of 6 uart's of AM335x processor present on ChiliSOM.
This fix moves declaration of uart0 from ChiliSOM to ChiliBoard, because
use of uart is strictly board-specific.

On these boards NAND ready pin status is avilable over
GPMC_WAIT0 pin.
For NAND we don't use GPMC wait pin monitoring but
get the NAND Ready/Busy# status using GPIOlib.
GPMC driver provides the WAIT0 pin status over GPIOlib.
Read speed increases from 7869 KiB/ to 8875 KiB/s
and write speed was unchanged at 5100 KiB/s.
Measured using mtd_speedtest.ko on am335x-evm.

The NAND Ready/Busy# line is connected to GPMC_WAIT0 pin and
can't be used for wait state insertion for NAND I/O read/write.
So disable read/write wait monitoring as per Reference Manual's

This reverts commit 8e6ebfaa9b.
Without the patch reverted regulators will not work. This prevents
MMC to be working for example so the boards can not boot to
MMC rootfs.
Tested it on beaglebone white and bisect also points to the
reverted commit.
The issue can be also fixed by adding "regulator-compatible =" to all board
dts file for the regulators.

Since this is a SOM (System on Module) that will be part
of another embedded board (and can't really exist on its own)
define it as a "dtsi" that will be included in the Device tree
describing the whole system later on.
Hardware specification:
* AM335x SoC
* up to 512 MB RAM
* NAND Flash (8x interface, cs0)
* UART0
* PMIC
* I2C0 (for PMIC)
