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

Since v3:
- fix build error reported by lkp@intel.com
- fix earlycon compatible string
- fix dtbs_check
- collect Reviewed-by tag

Since v2:
- fix dt_binding_check and dtbs_check warnings
- use uart_port_tx_limited() helper in uart driver
- collect Acked-by/Reviewed-by tag
- uart0 -> uart3
- update "riscv,ndev" property
- mv vendor prefix binding as the first patch
- add compatible string for bouffalolab bl808 plic

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
