soc/intel/cmn/xhci: Add function to reset the XHCI controller
This patch adds `xhci_host_reset()` to reset XHCI controller and the
scope of this function is with SMM hence, compiling xhci.c for SMM as
well.
Also, refactored `xhci.c` code to keep PCI enumeration within the scope
of `ramstage` alone hence, guarded with `ENV_RAMSTAGE` env_variable.
BUG=b:227289581
TEST=Able to perform a call from `xhci_host_reset` from S5 smi handler.
