arm64: dts: imx93-phyboard-segin: Add PEB-EVAL-01 overlay

Add overlay to support PEB-EVAL-01 adapter on phyBOARD-Segin-i.MX93.
This is a PHYTEC evaluation module with three LEDs and two input buttons
that users can attach to the board expansion connector X16.

Note that, due to compatibility with existing PHYTEC platforms using the
phyBOARD-Segin carrier board such as i.MX6UL and STM32MP1, we face some
hardware limitations and can thus only support one user LED (D2) and one
button (S2) on the i.MX93 variant of the phyBOARD-Segin.
