[PATCH v2 0/9] riscv: add Bouffalolab bl808 support

This series adds Bouffalolab uart driver and basic devicetrees for
Bouffalolab bl808 SoC and Sipeed M1s dock board.

It's too late for v6.2-rc1, but I hope I can catch up the v6.3-rc1
window.

I think I have addressed all review comments to v1, correct me if I
missed anything.

PS: this series assumes the "thead,c906" riscv cpu binding patch is
merged(I see Conor has picked up it).

Since v1:
- use FIELD_PREP and FIELD_GET macro
- rewrite bflb_uart_tx_chars()
- add vendor prefix for bouffalolab
- add dt binding for bl808 compatibles
- enable SOC_BOUFFALOLAB in defconfig
- collect Reviewed-by tag
- modify commit-msg as suggested
