* Support lazy install of sdk drivers
This patch adds support for lazy install of Marvell prestera SDK
drivers for platform-nokia. Lazy install for drivers is added as
updated sdk driver needs to classify the drivers required for platform
during compile time. SDK drivers and platform files are now fetched
from a submodule(mrvl-prestera).
Additionaly, DTB required for sonic_fit creation during compile time
is sourced from sonic-linux-kernel.

Add the create_only_config_db_buffers attribute to the DEVICE_METADATA|localhost. If the "create_only_config_db_buffers" exists and is equal to "true" - the buffers will be created according to the config_db configuration (for example BUFFER_QUEUE|* table), otherwise the maximum available buffers (which are read from SAI) will be created, regardless of the CONFIG_DB buffers configuration.

#### Why I did it
When a kernel crash occurs, the system will reboot to the kdump capture kernel if kdump is enabled (`config kdump enable`). In the kdump capture boot, it only stores the crash information, and then reboot the system to a normal boot.
In this boot, no SONiC service is started but it invokes `reboot` which is actually the SONiC reboot that depends on SONiC services. There is a logic to skip all SONiC stuff and invoke platform reboot in SONiC reboot to avoid issues.
However, on Nvidia platforms, the platform reboot still depends on SONiC services, which can cause issues.
So, the Debian reboot is called directly in platform reboot if it is invoked from the kdump capture boot.
#### How I did it
Manual test
Added support data for fabric monitoring in CONFIG_DB
The CONFIG_DB now has the FABRIC_MONITOR|FABRIC_MONITOR_DATA table for default value for fabric port monitoring. An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_MONITOR|FABRIC_MONITOR_DATA"
{'monErrThreshCrcCells': '1', 'monErrThreshRxCells': '61035156', 'monPollThreshIsolation': '1', 'monPollThreshRecovery': '8'}
The CONFIG_DB now also has a table for each fabric port for its isolate status.
An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_PORT|Fabric20"
{'alias': 'Fabric20', 'isolateStatus': 'False', 'lanes': '20'}
