x86/boot/e820: Print E820_TYPE_RAM entries as ... RAM entries
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
