x86: dts: Define a default TSC timer frequency If for some reason, TSC timer frequency cannot be determined from hardware, nor is it specified in the device tree, U-Boot will panic resulting in endless reset during boot. Let's define a default TSC timer frequency using the Kconfig value CONFIG_X86_TSC_TIMER_FREQ (note: #include must be used instead of /include/ otherwise the macro is not pre-processed).
