ARM: dts: keystone-k2l: Add PSC reset controller node
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.
