vm load: add SOS cmdline option for hugetlb

Browse Source 
adding "hugepagesz=1G" and "hugepages=X" into SOS cmdline, for X, current
strategy is making it equal
	e820_mem.total_mem_size -CONFIG_REMAIN_1G_PAGES
if CONFIG_REMAIN_1G_PAGES is not set, it will use 3 by default.

CONFIG_CMA is added to indicate using cma cmdline option for SOS kernel,
by default system will use hugetlb cmdline option if no CONFIG_CMA defined.
