thermal: devfreq_cooling: Make power a u64

The prototype of do_div() is:

uint32_t do_div(uint64_t *n, uint32_t base);

Make power u64 to avoid the following warning:

   drivers/thermal/devfreq_cooling.c: In function 'get_dynamic_power':
   drivers/thermal/devfreq_cooling.c:267:2: warning: comparison of distinct pointer types lacks a cast [enabled by default]
   drivers/thermal/devfreq_cooling.c:267:2: warning: right shift count >= width of type [enabled by default]
   drivers/thermal/devfreq_cooling.c:267:2: warning: passing argument 1 of '__div64_32' from incompatible pointer type [enabled by default]
   include/asm-generic/div64.h:35:17: note: expected 'uint64_t *' but argument is of type 'long unsigned int *'
