x86/boot/e820: Use 'enum e820_type' when handling the e820 region type

The E820 region type is put into four different types (!) when used in function
parameters or local variables:

	unsigned type;
	int type;
	unsigned long current_type;
	u32 type;

Use 'enum e820_type' in all these cases instead.

No change in functionality.
