drivers/generic/bayhub_lv2: remove unnecessary configs
coreboot sets up CLK_PM, ASPM, and L1ss automatically based on related
bits in "Link Capability Register" and "L1 PM Substates Capabilities
Register". coreboot overrides these configs even if the driver sets
them. Therefore, setting up CLK_PM, ASPM, and L1ss in the driver is
redundant and useless.
BUG=b:177955523
BRANCH=zork
TEST="lspci -vvvv" prints are identical with and without this patch;
LV2_LINK_CTRL(0x90) is 0x00110102 with and without this patch.
