Problem:
The 32-bit kernel cannot use the ramdump function.
Because the .text section is typically at 0x00108000,
which will be overwritten by the BL2E/BL33 after
reboot. And the PC side is unable to parse it.
Solution:
1. After kernel panic, use DMA to copy the 0-24MB
region to the 0x09000000 area.
2. Reboot to bl33z, fill compress_section[1] with
the 0x09000000 region.
3. Analyze it using the same method as before.

Problem:
For the low_mem project, the ramdump driver is
built-in. If many kernel configs are removed
during kernel size trimming, it may lead to build
errors in ramdump parsing info.
The removed configs info can be found in CL 486868.
Solution:
Romove parse info of kimage_voffset when ramdump
drv is built-in.
