mb/intel/tglrvp: Enable rp11 for optane
Optane memory module shows up as 2 NVMe devices in x2 config - NVMe storage
device and NVMe Optane memory. Storage device uses rp9 and optane memory
uses rp11. This patch enables rp11. Please note that these two share clk pins.
This is also dependent on pciecontroller3 config to be set as 2x2 instead of
1x4 in fit configuration in IFWI.
BUG=none
BRANCH=none
TEST=Build and boot tigerlake rvp board from Optane and check 2 NVMe devices
from lspci
