fix: revert "Panic if manifest isn't aligned."

This reverts commit 933fa55b88a868cc2c035906ae8a57a6889830cc.
libfdt doesn't handle unaligned memory accesses. There is an alignment
fault while dtb processing if dtb is 2 bytes aligned.

Revert of the original commit:
This reverts commit 1de06beb55e96a1722edf1ca8dfd75337f9a6ab2. Parsing
is now done by libfdt which handles unaligned memory accesses.

Original commit:
Panic if manifest isn't aligned.
Otherwise it will fail later on with a confusing error message.
