soc/intel: Deprecate SoC-specific global reset status configs

This change removes the SoC-specific `FSP_STATUS_GLOBAL_RESET_REQUIRED_X`
Kconfigs, as they are no longer necessary for handling FSP global reset
requests.

Previously, these Kconfigs were used to select a specific 32-bit reset
status code. However, with the introduction of FSP 2.4 and 64-bit
interfaces, the global reset status code can now vary between
architectures.

To address this, the FSP driver now sets the `FSP_STATUS_GLOBAL_RESET`
config to a common default value (depending upon most commonly used
global reset status code) based on the interface:
- 0x40000003 for 32-bit FSP interfaces
- 0x4000000000000003 for 64-bit FSP interfaces

This default can be overridden if an FSP implementation uses a
different status code (for example: Apollo Lake selects different FSP
reset status code as 0x40000005).

By removing the SoC-specific configurations, this change simplifies
global reset handling and ensures compatibility across different FSP
versions and platforms.

Below table shows the relationship between Platform, FSP and FSP Global
Reset Status:
+-----------------+--------------+-------------------------+
| Platform        |  FSP         |    Global Reset Status  |
+-----------------+--------------+-------------------------+
| Alder Lake      |  32-bit      |    0x40000003           |
+-----------------+--------------+-------------------------+
| Apollo Lake     |  32-bit      |    0x40000005           |
+-----------------+--------------+-------------------------+
| Cannon Lake     |  32-bit      |    0x40000003           |
+-----------------+--------------+-------------------------+
| Elkhart Lake    |  32-bit      |    0x40000003           |
+-----------------+--------------+-------------------------+
| Jasper Lake     |  32-bit      |    0x40000003           |
+-----------------+--------------+-------------------------+
| Meteor Lake     |  32-bit      |    0x40000003           |
+-----------------+--------------+-------------------------+
| Sky Lake        |  32-bit      |    0x40000003           |
+-----------------+--------------+-------------------------+
| Tiger Lake      |  32-bit      |    0x40000003           |
+-----------------+--------------+-------------------------+
| Panther Lake    |  64-bit      |    0x4000000000000003   |

BUG=b:347669091
TEST=Verified FSP requested global reset functionality on google/rex0
(32-bit) and google/rex64 (64-bit) platforms.

w/ 32-bit FSP:

```
(Wdt) AllowKnownReset
[FspResetSystem2] FSP Reset Initiated
FSP returning control to Bootloader with reset required return status
40000003
FSPS, status=0x40000003
FSP: handling reset type, status=0x40000003
GLOBAL RESET!
global_reset() called!
HECI: Global Reset(Type:1) Command
```

w/ 64-bit FSP:

```
(Wdt) AllowKnownReset
[FspResetSystem2] FSP Reset Initiated
FSP returning control to Bootloader with reset required return status 3
FSPS, status=0x4000000000000003
FSP: handling reset type, status=0x4000000000000003
GLOBAL RESET!
global_reset() called!
HECI: Global Reset(Type:1) Command
```
