Merge https://gitlab.denx.de/u-boot/custodians/u-boot-riscv
- Sipeed Maix support S-mode. - Provide command sbi. - Use fdtdec_get_addr_size_auto_parent to get fu540 cache base address. - Fix a compiler error with CONFIG_SPL_SMP=n. - Fix sifive ram driver 32 compiler warnings. - Fix kendryte/pll.h redefine nop() warning.
