Since use physical address directely, so acpi_os_map_memory()

Reading three times is redundant, but reading two times is needed.
Becasue the ACPI code run very stable, but we need more information
before that.
As for Masa's issue, I am wondering whether we can tranfer the
information or only the address of SRAT table from compressed period
to the period after start_kernel().

e length of memory is 8. Well the max memory address is 16, add
"0x" and '\0' is 19. So I set it as 20.
I am not sure whether 8 is enough for the address, if OK, 11 will
be enough, or 19 is OK.
If my understanding is wrong, please tell me.

if (!data)

else {
