    arm/exynos: Allow releasing UART retention for resume.
    
    The UART / serial console is put in retention state by kernel during suspend /
    resume path, which caused Coreboot not able to print any messages during resume.
    
    Sending values to the padret_uart_opt inside PMU may release UART, but that may
    also cause unexpected output when kernel is back. However, it's still very
    helpful when we are debugging suspend/resume inside Coreboot.
    
    To get UART message on resume, call wakeup_enable_uart() in boot block or
    romstage (before console_init).
