MTTCAN as a Kernel Built-in Driver

When you build the MTTCAN driver along with the kernel, it is part of the kernel binary.

Follow the steps above in MTTCAN as a Module.
Set the following CONFIG options in defconfig.
For additional information, refer to Compiling the Kernel (Kernel 5.15).
```
CONFIG_CAN=y
CONFIG_CAN_RAW=y
CONFIG_CAN_DEV=y
CONFIG_MTTCAN=y
```
Alternatively, these options can be set as described in Compiling the Kernel (Kernel 5.15), steps 1-3, to:
- Setup the environment macros
- Set the kernel source directory
- Create an output directory and configure the kernel for the board

Execute the following command.

make -C kernel O=${PWD}/out-linux 
DEFCONFIG_PATH=$PWD/t23x/arch/arm64/configs menuconfig
[*] Networking support --->
    <M> CAN bus subsystem support ---> 
    <M> Raw CAN Protocol (raw access with CAN-ID filtering)
    <M> CAN Device Drivers --->
    <M> Platform CAN drivers with Netlink support
    <M> Bosch M_TTCAN Devices

Exit and save.
Build the kernel and copy the modules from the kernel Image and zImage as follows:
```
cp ${PWD}/out-linux/arch/arm64/boot/zImage
 <top>/drive-linux/kernel
cp ${PWD}/out-linux/arch/arm64/boot/Image 
<top>/drive-linux/kernel
```

Reflash the target system.
