soc/intel/skylake: Initialize UART based on CONFIG_UART_DEBUG

Current implementation checks for CONFIG_BOOTBLOCK_CONSOLE and then
    initializes UART. If only CONFIG_BOOTBLOCK_CONSOLE
    is enabled without enabling CONFIG_UART_DEBUG, there are
    compilation issues. This is the case when using SIO UART for Skylake
    DT platform. Hence initialize UART when CONFIG_UART_DEBUG is enabled
    and not based on CONFIG_BOOTBLOCK_CONSOLE.

Also move BOOTBLOCK_CONSOLE out from UART_DEBUG to CPU_SPECIFIC_OPTIONS
    as part of the fix needed.
