e820__mapped_all() is passed as a callback to is_mmconf_reserved(),
which expects a function of type:
typedef bool (*check_reserved_t)(u64 start, u64 end, unsigned type);
However, e820__mapped_all() accepts enum e820_type as the last argument
and this type mismatch trips indirect call checking with Clang's
Control-Flow Integrity (CFI).
As is_mmconf_reserved() only passes enum e820_type values for the
type argument, change the typedef and the unused type argument in
is_acpi_reserved() to enum e820_type to fix the type mismatch.
