Host ACPI parsing is needed during initialization only, not in run time.
Hence we don't need to clear U flag for memory in reserved or ACPI type
E820 entries.
- move enable_smep() and enable_smap() to the end of init_pcpu_post(),
so stac()/clac() can be removed from any init code before this point.
- call init_seed() before init_pcpu_post(), and rmeove stac()/clac() from
init_seed().

SMAP protection.This patch is to remove these cases.

- for all cases of referring guest bootargs size, replace MEM_2K with
CONFIG_MAX_BOOTARGS_SIZE for better readability.
- remove duplicated MAX_BOOTARGS_SIZE definition from vm_config.h.
Also fix one minor issue in general_sw_loader() which uses copy_to_gpa()
to copy a string. Since copy_to_gpa() makes use of memncpy_s() to do the
job, the size parameter should include the string null ternimator.
