The Power Sleep Controller (PSC) module contains specific
memory-mapped registers that can be used to perform reset
management using specific bits for the DSPs available on the
SoC. The PSC is defined using a syscon node, and the reset
functionality is defined using a child syscon reset controller
node.
Add this syscon reset controller node as well as the reset
control data for the resets it supports for the 66AK2L SoCs.

The Keystone 2 boot monitor uses 32 KB of the MSM RAM @ 0x0c1f8000
on 66AK2L SoCs, so add a reserved child node for the same.
This address is aligned to the values used within the latest boot
monitor firmware [1] as of commit cf8b431e8b3b ("soc: Move load
address to end of MSMC").

Add the RAM managed by the Multicore Shared Memory Controller (MSMC)
as a mmio-sram node. The 66AK2L SoCs have 2 MB of such memory. Any
specific MSM memory range needed by a software module ought to be
reserved using an appropriate child node.

The TI Keystone SoCs have extra UART registers beyond the standard 8250
registers, so we need a new compatible string to indicate this. Also, at
least one of these registers uses the full 32 bits, so we need to specify
reg-io-width in addition to reg-shift.
"ns16550a" is left in the compatible specification since it does work as
long as the bootloader configures the SoC UART power management registers.

Drivers using pinctrl-single,pins have #pinctrl-cells = <1>, while
pinctrl-single,bits need #pinctrl-cells = <2>.
Note that this patch can be optionally applied separately from the
driver changes as the driver supports also the legacy binding without
#pinctrl-cells.

Add pinctrl node and populate the pinctrl registers with the default
values.

As reported in [1], rename the k2* dts files to keystone-* files
this will force consistency throughout.
Script for the same (and hand modified for Makefile and MAINTAINERS
files):
for i in arch/arm/boot/dts/k2*
do
b=`basename $i`;
git mv $i arch/arm/boot/dts/keystone-$b;
sed -i -e "s/$b/keystone-$b/g" arch/arm/boot/dts/*[si]
done
NOTE: bootloaders that depend on older dtb names will need to be
updated as well.
