crypto: qat - remove BITS_IN_DWORD()

The BITS_IN_DWORD() macro, which represents the number of bits in the
registers accessed by the firmware loader, is currently defined as 32.

For consistency and readability, replace this macro with the existing
BITS_PER_TYPE() macro, which serves the same purpose.

This does not introduce any functional change.
