Merge branch 'master' of https://gitlab.denx.de/u-boot/custodians/u-boot-riscv

- No need to check before free in kendryte clk.
- Only enable OF_BOARD_FIXUP if U-Boot is configured for S-Mode.
- Reduce k210 dts DMA block size
- Move timers into drivers/timer
- Correct fu540 dts reg size of clint node
