Commit b430428a ("8250: Don't clobber spinlocks.") introduced a regression on the parisc architecture, which broke the handover to the serial port at boottime. early_serial_setup() was changed to only copy a subset of the uart_port fields, and sadly the "type" and "line" fields were forgotten and thus the serial port was not initialized and could not be used for a handover. This patch fixes this by copying the missing fields. As this change to early_serial_setup() doesn't need an initialized spinlock in the uart_port struct any longer, we can drop the spinlock initialization in the superio driver.
