dts: atmel sam4s: fix sram address

MichalMyczkowski · kartben · commit 3a53845fadef · 2025-02-06T17:47:31.000+01:00
Changed Atmel SAM4S series sram adress from 0x20100000 to 0x20000000. Now it matches what is in Atmel SAM4S Series Datasheet chapter 8 section 1.1 Internal SRAM: https://ww1.microchip.com/downloads/aemDocuments/documents/OTH/ProductDocuments/DataSheets/Atmel-11100-32-bitCortex-M4-Microcontroller-SAM4S_Datasheet.pdf#G1.1069257 Fixes #85211.
