ACPI / LPSS: provide con_id for the clkdev
Commit 7d78cbefaa (serial: 8250_dw: add ability to handle the peripheral clock) introduces handling for a second clk to 8250_dw.c which is the driver also for LPSS UART. The second clk forces us to provide identifier (con_id) for the clkdev we create. This fixes an issue where 8250_dw.c is getting the same handler for both clocks.
