rockchip: Set default LNX_KRNL_IMG_TEXT_OFFSET_BASE to SYS_TEXT_BASE
U-Boot can be chainloaded from vendor firmware on ARM64 chromebooks from
a GPT partition (roughly the same as in doc/chromium/chainload.rst), but
an appropriate image header must be built-in to the U-Boot binary by
enabling LINUX_KERNEL_IMAGE_HEADER.
This header has a field for an image load offset from 2MiB alignment
which must also be customized through LNX_KRNL_IMG_TEXT_OFFSET_BASE.
Set it equal to SYS_TEXT_BASE by default for Rockchip boards, which
happens to make this offset zero and works fine on chromebook_kevin
both for chainloading and bare-metal use.
