cpu,mb,soc: Init missing lb_serial struct fields

Initialize the input_hertz and uart_pci_addr fields of the lb_serial
struct to prevent later undefined reads in lb_add_serial(). This was
done for exynos5420 in commit ff94e00362 (soc/samsung/exynos5420/uart.c:
Init new serial struct variables), and this patch finishes the rest.
Note that not all of the drivers can have the UART PCI address
configured at build time, so a follow-up patch will be needed to correct
those ones.
