In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.
This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.
The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

If CONFIG_AUDIO_CODEC_WOV is enabled and the builder can access the EC
private repository, then compile with speech-micro. Otherwise, there
are dummy implementations for speech-micro API.

IPI table is board-specific. This CL removes the original
IPI table in chip layer, and uses gen_ipi_table to generate
the table for each board to reduce the maintenance effort.
TEST=make BOARD=kukui_scp, and see build/kukui_scp/ipi_table_gen.inc
exists. Push to Kukui, and see SCP boots.
TEST=modify IPI_COUNT in board.h and see it generates a new
ipi_table_gen.inc

Removes stepping_stone regions, and move ROM_BASE from 0x800 to 0x0.
stepping_stone region is to smooth SCP's bringing up stage for
being compatible with both original and new implementation.
Now that we have done the kernel side driver implementation,
we can earn more SRAM space by removing the stepping_stone.
TEST=run SCP on kukui, and see it boots.

SCP assumes vector table at CONFIG_RAM_BASE. However, on cortex-m
resetting, it would load 0x0 to SP(r13) and load 0x04 to PC(r15).
Stepping stones copy these two very special values from CONFIG_RAM_BASE,
CONFIG_RAM_BASE + 0x04 to 0x0, 0x4 resepctively.
TEST=make BOARD=kukui_scp -j, and see the value from 0x0, 0x4 in
kukui_scp/RW/ec.RW.flat are the same as 0x800, 0x804 respectively.
TEST=Puts ec.RW.bin on kukui and see that SCP boots.
