staging: rts5208: Remove RTSX_READ_REG and RTSX_WRITE_REG macros

Macros with hidden flow control are bad form as the code path
taken can be unexpected for the reader.

Expand these in-place and remove the macros.

Done with coccinelle script:

expression chip;
expression arg1;
expression arg2;
expression arg3;

-	RTSX_WRITE_REG(chip, arg1, arg2, arg3);
+	retval = rtsx_write_register(chip, arg1, arg2, arg3);

+		return retval;
