Description:
In the document, range of innodb_ft_sort_pll_degree is 1 to 32.

I set parameter innodb_ft_sort_pll_degree in my.cnf to 25 or 11. after restart service, the value of innodb_ft_sort_pll_degree is 16 using 'show variables like `innodb_ft_sort_pll_degree `';

I tested other values and found that the value of innodb_ft_sort_pll_degree could only be set to 1,2,4,8,16 ,wheather in 5.6/5.7/8.0

How to repeat:
1. set the value of innodb_ft_sort_pll_degree to 25
2. restart the service
3. show variables like 'innodb_ft_sort_pll_degree '

Suggested fix:
The document should be consistent with the real value range
