Add pinctrl data for ddr_vtt_toggle pin so that it is configured
for proper state during DeepSleep0. The pin should enter DS0 off mode
and hold the line low so VTT regulator is kept off while suspended.
It is also important for the PULLUP to be set on this pin so that
on removal of isolation, the VTT line is pulled high as a requirement
for bringing the DDR3 out of self-refresh.
This toggling is dependent on the IO isolation controlled by the
wkup_m3. Without placing the IOs into isolation the DS0 states set for
the pin will not be latched into effect during suspend.

There are several pins on this EVM that are not in use but they can
still draw power if misconfigured. Create a pinctrl entry for these pins
and configure each one for optimal power savings.

Currently uart0 uses pinctrl config set by bootloader so
create default state that can be restored after a suspend
event.
Also, modify uart0 pinctrl to include RTS and CTS pins as by
default these are not in a mode for optimal power savings.

Add pinctrl settings so that gpio0 wake from suspend will be supported
using buttons SW4 and SW7. Also, add pinctrl configuration for 0x954,
spi0_d0, which is an unused pin brought out to a header on the board
that in it's default state also connects to the gpio used for wakeup,
gpio0_3, which affects the state of the pin and prevents a working
wakeup unless we set the mux to a different state.

Add sleep state for beeper pins. Without this there was a power
increase during the suspend and standby states on V3_3D domain.
