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

Message

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
