Is there a reason we can't just move the dtt_init() call to after
relocation to RAM for both the cases with and without CONFIG_POST
defined?  If some POST relies on the temperature sensors being
initialized it seems cleaner to change the POST to run after relocation
than add more ifdefery to common code.

Unconditionally moving dtt_init() to after relocation would also allow
dtt drivers to use global variables, etc (which it just so happens an
lm90-type driver I'm working on requires:).

Best,
Peter
