drivers: eSPI: add eSPI driver support for NPCX7 series. In npcx7 series, all of them support the Intel Enhanced Serial Peripheral Interface (eSPI) Revision 1.0. This specification provides a path for migrating host sub-devices via LPC to a lower pin count, higher bandwidth bus. In addition to Host communication via the peripheral channel, it provides virtual wires support, out-of-band communication, and device mastering option over the Chipset SPI flash. Becisdes introducing eSPI device in npcx7, this CL also includes: 1. Add eSPI device tree declarations. 2. Add npcx7-espi-vws-map.dtsi to present the relationship between eSPI Virtual-Wire signals, eSPI registers, and wake-up input sources. 3. Zephyr eSPI api implementation. 4, Add OOB (Out of Band tunneled SMBus) support. 5. Add configuration files for eSPI test suites. Signed-off-by: Mulin Chao <MLChao@nuvoton.com>
