mb/google/rex: 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 ~40 ms.
Boot time data
Before:
* 955:returning from FspSiliconInit 1,656,985 (274,416)
After:
* 955:returning from FspSiliconInit 1,593,036 (233,286)
BUG=b:252410202
TEST=Verified that boot time is reduced by ~40 msec.
