dm: fix LPC UART no output issue after reboot 

The meaning of lpc_uart_vdev::enabled was changed from runtime enablement
status of UARTs to user configuration in commit 852f10cc3. So it's
incorrect to clear it in lpc_deinit() which will cause UARTs disabled
after reboot.

Tracked-On: #8537
Fixes: 852f10cc3 ("dm: lpc: only emulate COM ports specified in command line")
