it83xx: espi: Don't reset PNPCFG while PLTRST_L asserted
The PNPCFG (EC2I control module) is used to set I/O port base
address and IRQ number.
On it8320, PNPCFG will be reset while system event PLTRST_L
is asserted. This means we can't decode I/O cycles correctly
until we re-initialize PNPCFG.
We disable this reset source, then we don't need to re-initialize
PNPCFG for each PLTRST_L asserted.
BRANCH=none
BUG=none
TEST=MECC board with it8320 + Intel SKL-Y RVP3 and boot to shell.
