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.

This reverts commit 4ac1d81e1430dbfbfba1376a23ab19dfa845d7ef.
The config name collides with the same config name in zephyr.
Also, renames zephyr Kconfig CONFIG_PLATFORM_EC_FLASH to
CONFIG_PLATFORM_EC_FLASH_CROS as the corresponding change at Kconfig
side.

The task stack size of is small enough that the process was triggering
stack overflows when responding to commands. These actions had a small
chance of causing EC hardfaults. This was apparent with the gpioget
command which had the attributes of performing many calls to a printf
function which also has many parameters.
Since the structure of a printf with 10 or more parameters is common
when constructing console responses, this enlarges the stack for that
task. This is more important since the probability of it creating a
hardfault is low. To reduce the chance of this issue on other platforms,
the platforms with 488 byte tasks were also enlarged to 512 bytes.

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.
