[ Upstream commit 829e2a23121fb36ee30ea5145c2a85199f68e2c8 ]

The data conversion is done rather by a wrong function.  We convert to
BE32, not from BE32.  Although the end result must be same, this was
complained by the compiler.

Fix the code again and align with another similar function
tas2563_apply_calib() that does already right.
