Sync rk3399-rock-pi-4 related device tree from linux v6.8.
Add SPI flash related options to support booting from SPI flash.
Add AHCI=y, SCSI_AHCI=y, AHCI_PCI=y and SCSI=y to support PCIe SATA boot.
As we know, these boards have no standard connectors for PCI Express expansion cards, which makes me wonder how many users actually use M.2 PCI Express modules with SATA controllers on them with these boards, and need support for them in U-Boot?
I mean, it can't hurt, but frankly, I'm not 100% sure about it.
With the M.2 Extension Board [1] and a M.2 to PCIe X4 adapter it is very easy to convert the M.2 slot into a standard PCIe X4 slot and use it with a PCIe SATA card. At least that is how I have tested and used this.
I do think there will be many users of PCIe AHCI/SATA, but with this series I try to get all boards to have same feature set as long as there is some way to use a feature.

Change to SPL_MAX_SIZE=0x40000, SPL can be up to 256 KiB.
Add ROCKCHIP_IODOMAIN=y to configure io-domain voltage.
Add PHY_REALTEK=y and DM_ETH_PHY=y to support ethernet PHY.
Remove SPL_TINY_MEMSET=y to use full memset in SPL.

Otherwise, looking good to me.
