servo: sentry: Reuse JTAG pins for PD MCU UART.

Sentry is a skylake board and in order to talk to the PD MCU, the JTAG
pins have been repurposed as the UART pins for interface 1.

Without this change, the usbpd_uart_pty will fail to initialize.

TEST=cros_workon start hdctools; sudo emerge hdctools; sudo servod -b
sentry and verify that servod starts successfully.
