mm: introduce helper function mem_init_print_info() to simplify mem_init()
Introduce helper function mem_init_print_info() to simplify mem_init()
across different architectures, which also unifies the format and
information printed.
Function mem_init_print_info() calculates memory statistics information
without walking each page, so it should be a little faster on some
architectures.
Also introduce another helper get_num_physpages() to kill the global
variable num_physpages.
