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.
