Add espi_signal_is_vw in new file common/espi.c for
testing if a signal is an eSPI virtual wire. API used
in power common and intel_x86.
Fix CONFIG_BRINGUP support for eSPI (off by default).
Add espi_vw_get_wire_name returning a pointer to
constant string. Chip modules do not need to maintain
names of eSPI signals.
