soc/intel/tigerlake: Enable long cr50 ready pulses
A new Kconfig setting CR50_USE_LONG_INTERRUPT_PULSES controls new code
running in verstage, which will program a new Cr50 register, to
have Cr50 generate longer than default interrupt pulses.
This needs to be selected on all Tiger Lake systems, since Tiger Lake
(and likely future Intel SoCs) require at least 100us interrupt pulses.
