[PATCH 08/32] x86/boot/e820: Print E820_TYPE_RAM entries as ... RAM entries

[Ingo Molnar <mingo@kernel.org>]

So it is a bit weird that the actual RAM entries of the E820 table
are not actually called RAM, but 'usable':

	BIOS-e820: [mem 0x0000000000100000-0x000000007ffdbfff]    1.9 GB usable

'usable' is pretty passive-aggressive in that context and ambiguous,
most E820 entries denote 'usable' address ranges - reserved ranges
may be used by devices, or the platform.

Clarify and disambiguate this by making the boot log entry
explicitly say 'System RAM', like in /proc/iomem:

	BIOS-e820: [mem 0x0000000000100000-0x000000007ffdbfff]    1.9 GB System RAM
