net: dsa: lan9303: lan9303_csr_reg_wait cleanups
Non-functional cleanups in lan9303_csr_reg_wait():
- Change type of param 'mask' from int to u32.
- Remove param 'value' (will probably never be used)
- Reduced retries from 1000 to 25, consistent with lan9303_read_wait.
- Removed comments

Changes v1 -> v2:
- Removed comments
