ARM: dts: aspeed: everest: Add reserved memory for TPM event log

Browse Source 
Trusted boot support requires the platform event log passed up
from the bootloader. In U-Boot, this can now be accomplished with
a reserved memory region, so add a region for this purpose to the
Everest BMC devicetree.
