Existing implementation adds the CSE RW update binary to FW_MAIN_A/B
regions and this has significant impact on boot time due to the
increase in the size of these regions leading to higher loading
and hashing time.
This patch modifies flash layout to add new ME_RW_A/B fmap regions
in the RW_SECTION_A/B.
BUG=b:169077783
TEST= Built for dedede. Verified that CSE RW binary is added to the
CSE_RW_A/B fmap region.

RW_LEGACY region needs to be 1 MiB to accommodate any alternate
firmware. Hence update the flash ROM layout as below:
* Grab ~512 KiB from each FW_MAIN_A/B regions and allocate them to
RW_LEGACY region so that it grows to 1 MiB.
* Remove VBLOCK_DEV region which is not used.
* Re-size the ELOG region to 4 KiB since that is the maximum size of the
ELOG mirror buffer.
* Resize RW_NVRAM, VBLOCK_A/B regions to 8 KiB since no more than that
size is used in those regions.
* Resize SHARED_DATA region to 4 KiB since no more than that size is
used in that region.
* Based on the resizing, allocate each FW_MAIN_A/B regions with 72 KiB.

TEST=Build and boot to OS in Drawlat. Ensure that the firmware test
setup and flash map test are successful. Ensure that the event logs are
synced properly between reboots. Ensure that the suspend/resume sequence
is working fine. Ensure that the ChromeOS firmware update completes
successfully for the boot image with updated flash map and the system
boots fine after the update.

Upcoming variant boards will use 16 MiB SPI ROM. So add support for 16
MiB flash map descriptor.
BUG=b:155107866,b:152981693
TEST=Build different variant boards. Ensure that waddledoo which is using
32 MiB SPI ROM boots.
