soc/apollolake/uart.c: Do not NOOP .set_resources() and friends

When SOC_UART_DEBUG was not set, the boot would hang somwhere in
ramstage, as evidenced by POST codes reported from the EC. This was
traced to the .set_resources and .enable_resources members of the UART
PCI driver being set to NOOP.
Although the exact mechanism of failure is not known, this change
eliminates the hang.
