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.
