mb/intel/adlnrvp: Skip sending the MBP HOB to save boot time
This change is to skip sending the MBP HOB since coreboot doesn't
use it and also helps to reduce the boot time by ~40msec on ADL-N.
Boot time data:
Before:
* 955:returning from FspSiliconInit 956,832 (110,268)
After:
* 955:returning from FspSiliconInit 944,528 (74,213)
BUG=b:241850107
TEST=Verified that boot time is reduced by ~40msec and also S0i3
is working.
