[PATCH] clk: renesas: r8a7740: Remove an unused field in struct div4_clk

[Christophe JAILLET]

In "struct div4_clk", the 'flags' field is unused.

Remove it and update the 'div4_clks' array accordingly.

Found with cppcheck, unusedStructMember.

Compile tested only.

Apparently, it has never been used. It is not a left-over from a
refactoring. I don't if it is supposed to be used somewhere in the driver.

Should it help the review, renesas/clk-r8a73a4.c has a very similar
construction and also a struct div4_clk without this 'flags' field.
