davinci: Remove ineffective BOARD_KERNEL_OFFSET variable

Browse Source 
Remove various variables related to where kernel and ramdisk are loaded
by the bootloader. There are two reasons for this:

1. The B1C1 bootloader ignores all the offset values for kernel, ramdisk
and tags. The default B1C1 memory layout has been designed to accomodate
a larger KASAN kernel.

2. The variables BOARD_KERNEL_TAGS_OFFSET and BOARD_RAMDISK_OFFSET are
ignored by the Android build system (unless they are copied into the
BOARD_MKBOOTIMG_ARGS variable). This is in contrast to the variables
BOARD_KERNEL_BASE, BOARD_KERNEL_PAGESIZE and BOARD_MKBOOTIMG_ARGS which
are referenced by build/make/core/Makefile
