soc/intel/common/cse: skip heci_init() if HECI1 is disabled
If the HECI1 PCI device is disabled, either via devicetree or other
method (HAP, me_cleaner), then we don't want/need to program a BAR,
set the PCI config, or call heci_reset(), as the latter will result
in a 15s timeout delay when booting.
Test: build/boot Purism Librem 13v2, verify heci_reset()
timeout delay is no longer present.
