npcx7_evb: Add initial board driver of npcx7 ec evb.

Add the evaluation board driver of npcx7 series ec for testing. If you
received the evb which ec is 128-pins package, please notice it has
the following limitations.

a. No GPIOD7/E0 pins.
b. No I2C4_0, I2C4_1, I2C5_1 and I2C6_1 ports.
c. No ADC7, ADC8 and ADC9 channels.
d. No JTAG port 1.
e. Do not enable CONFIG_HIBERNATE_PSL since no PSL circuit on evb.

This CL also includes:
1. Modified reset config from srst to sysresetreq in openocd/npcx.cfg.
   Make sure openocd driver can reset ec by using NVIC_SYSRESETREQ.
2. Add flash utilities for npcx7 ec in openocd/npcx_cmds.tcl.
3. Add npcx7_evb support in flash_ec.

BRANCH=none
BUG=none
TEST=Passed all npcx7 drivers verification on the evb no matter which
     ec's package is 128 or 144 pins package.
