clk: sunxi-ng: Constify struct ccu_reset_map
'struct ccu_reset_map' are not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename

After:
=====
text data bss dec hex filename
1597 2160 0 3757 ead drivers/clk/sunxi-ng/ccu-sun20i-d1-r.o
