mseal: remove can_do_mseal()
No code logic change.
can_do_mseal() is called exclusively by mseal.c, and mseal.c is compiled
only when CONFIG_64BIT flag is set in makefile. Therefore, it is
unnecessary to have 32 bit stub function in the header file, remove this
function and merge the logic into do_mseal().
