servo: lucid: rename cpu_uart to ec_uart.
Lucid uses the cosmos flex to connect to servo but with its EC uart
connected to uart2 (cpu). This CL renames those controls to 'ec_uart_'
such that automated scripts (flash_ec) and developers can locate the
proper uart.
BUG=chrome-os-partner:43619
TEST=manual
1. launch servod
sudo servod -b lucid
2. verify that both cpu & ec uart controls map to same control (interface 8)
dut-control -i | egrep -A 2 "(cpu|ec)_uart_(pty|parity|buadrate|bits|sbits|en)"
