UltraRISC DP1000 integrates a Synopsys DesignWare APB UART, but it does
not provide the standard CPR and UCV registers.

The UltraRISC DP1000 UART does not provide the standard CPR register used
by 8250_dw to discover port capabilities.

Provide a fixed CPR value for the DP1000-specific compatible so the
driver can configure the port correctly.
