Add support for ESWIN EIC7700 SoC consisting of SiFive Quad-Core
P550 CPU cluster and the first development board that uses it, the
SiFive HiFive Premier P550.

This patch series adds initial device tree and also adds ESWIN
architecture support.

Boot-tested using intiramfs with Linux 6.15.0-rc1 on HiFive Premier
P550 board using U-Boot 2024.01 and OpenSBI 1.4.

Changes in v3:
- Rebased the patches to kernel 6.15.0-rc1
- Added "Reviewed-by" tag of "Rob Herring" for Patch 4
- Updated MAINTAINERS file
- Add GIT tree URL
- Updated DTSI file
- Added "dma-noncoherent" property to soc node
- Updated GPIO node labels in DTSI file
- Link to v2: https://lore.kernel.org/lkml/20250320105449.2094192-1-pinkesh.vaghela@einfochips.com/

Changes in v2:
