Subject: cros_ec: Increase command timeout for flash erase
X-Git-Tag: v2025.01-rc5-pxa1908~2127^2~1

cros_ec: Increase command timeout for flash erase

Erasing the flash can take over a second on some devices and the EC is
not responsive during this time. Update the timeout to 5 seconds to cope
with this.
