Subject[PATCH 1/4] clk: versaclock3: Remove redundant _is_writeable()
The versaclock3 driver provides an _is_writeable() function which returns
true for all registers. This is the default assumption for regmaps so we
can remove the function for a very minor improvement in performance and
code size.
