soc/intel/pantherlake: Enable FSP debug log level control using CBFS

This commit enables the FSP_DEBUG_LOG_LEVEL_USING_CBFS Kconfig option
for Panther Lake ChromeOS devices.

This allows controlling the FSP debug log level using CBFS RAW binary
files, providing more flexibility in debugging silicon firmware issues
with a debug AP FW binary.

The following CBFS files are used to determine the log levels:

- fsp_pcd_debug_level: For the overall FSP debug log level.
- fsp_mrc_debug_level: For the MRC (Memory Reference Code) debug log
  level.

This capability is particularly useful when debugging issues that require
examining both silicon and MRC logs simultaneously.

BUG=b:227151510
TEST=Able to control the FSP debug log based on CBFS options

To inject the fsp_pcd_debug_level and fsp_mrc_debug_level CBFS files
with the desired log level, run:

```
cbfstool image-fatcat.serial.bin add-int -i 5 -n option/fsp_pcd_debug_level

cbfstool image-fatcat.serial.bin add-int -i 5 -n option/fsp_mrc_debug_level
```
