rtc: sysfs: fix a cast removing the const attribute
The char pointer buf_ptr is assigned an address from a const char pointer buf (parameter of wakealarm_store). The data pointer by buf_ptr is never modified. So casting it to a (char *) is useless. This patch remove this cast, and transform buf_ptr to a const char pointer.
