x86/boot/e820: Use bool in query APIs

Browse Source 
Change e820__mapped_any() and e820__mapped_all()'s return type and
e820__range_remove()'s check_type parameter to bool.

Propagate it into arch/x86/pci/mmconfig-shared.c as this change
affects a function signature there too.

No change in functionality.
