----------------------------------------------------------------
RISC-V Devicetrees for v6.20

Sophgo:

For CV18xx serials:
Update RX/TX FIFO size to fix the USB transfer issue.

For SG2042:
Optimize the DTS file format, including moving PLIC/CLINT
nodes into cpu dtsi and sorting peripheral nodes by address.
In addition, we also enable RTC for Pioneerbox.

For SG2044:
Add "b" ISA extension to fix dtbs_check warnings.
