RISCV: dts: starfive: Change wr/rd_osr_lmt value from 4 to 0xf

Change wr/rd_osr_lmt value from 4 to 0xf.
When value is using to 4, ethernet Rx Performance is decreasing.

Vendor kernel(v5.15) is using its value as 0xf.

The below is iperf result.
- Using to 4   - Rx is 45MBits/sec, Tx is 980MBits/sec
- Using to 0xf - Rx is 750MBits/sec, Tx is 930Mbits/sec
