x86/boot/e820: Rename e820_table_saved to e820_table_firmware and improve the description
So the 'e820_table_saved' is a bit of a misnomer that hides its real purpose.
At first sight the name suggests that it's some sort save/restore mechanism,
as this is how we typically name such facilities in the kernel.
But that is not so, e820_table_saved is the original firmware version of the
e820 table, not modified by the kernel. This table is displayed in the
/sys/firmware/memmap file, and it's also used by the hibernation code to
calculate a physical memory layout MD5 fingerprint checksum which is
invariant of the kernel.
So rename it to 'e820_table_firmware' and update all the comments to better
describe the main e820 data strutures.
Also rename:
'initial_e820_table_saved' => 'e820_table_firmware_init'
'e820_update_range_saved' => 'e820_update_range_firmware'
... to better match the new nomenclature.
No change in functionality.
