mb/google/nissa: Disable SOC_INTEL_CSE_PRE_CPU_RESET_TELEMETRY
On nissa, the pre-x86 time is not part of the 1s firmware boot time
target. Including the pre-x86 timestamps causes confusion since the boot
time appears to be greater than 1s, so disable the Kconfig on nissa.
We're not doing any analysis or optimisation of the pre-x86 time on
nissa anyway, this work will start from MTL onwards. Also, the Kconfig
is already disabled on the brya firmware branch, so this will result in
the same behaviour as brya.
Before:
Total Time: 1,205,840
After:
Total Time: 995,300
BUG=b:239769532
TEST=Boot nivviks, check "1st timestamp" is the first timestamp.
