poppy: Increase console buffer size to 4096 bytes
Increase the size from 1024 to 4096 to reduce the likelihood of
overflows. To make space for the larger buffer, we reduce
CONFIG_ACCEL_FIFO to 512 entries (from 1024 entries: saves 4096
bytes of RAM).
grep shared_mem_buf build/lux/RW/ec.RW.smap
Before this patch:
200c74e0 D __shared_mem_buf
After this patch:
200c70e0 D __shared_mem_buf
(we saved 1024 bytes of RAM)
BRANCH=poppy
BUG=b:77159941
TEST=Flash lux, see that we do not lose EC logs in /var/log/cros_ec.log.
