nuc: Enable JTAG directly by NPCX_ENABLE_JTAG definition
Enable JTAG functionality by SW without pulling down strap-pin nJEN0 or nJEN1
during ec POWERON or VCCRST reset occurs.
Please notice it will change pinmux to JTAG directly.
Modified drivers:
1. gpio.c: Remove JTAG0/1 alternative groups and bits from gpio_alt_table
2. jtag.c: Enable JTAG functionality
BUG=chrome-os-partner:34346
TEST=make buildall -j; test nuvoton IC specific drivers
