soc/intel/adl: Add missing claimed memory regions
The Alder Lake chipset has several more reserved memory regions that
are unavailable to the resource allocator than are currently marked
as such in the system agent code. This CL adds the following regions
(documented in Intel docs #626540, #619503):
1. TSEG
2. GSM
3. DSM
4. PCH_RESERVED
5. CRAB_ABORT
6. APIC
7. TPM
8. LT_SECURITY

BUG=b:149830546
BRANCH=firmware-brya-14505.B
TEST='emerge-brya coreboot chromeos-bootimage' builds correctly.
Tested on an Anahera device which successfully boots to ChromeOS
with kernel version 5.10.109-15688-g857e654d1705. Also ran dmseg,
and saw the added regions in e820 prints.
