crypto: qat - add macro to write 64-bit values to registers

Introduce the ADF_CSR_WR_LO_HI macro to simplify writing a 64-bit values
to hardware registers.

This macro works by splitting the 64-bit value into two 32-bit segments,
which are then written separately to the specified lower and upper
register offsets.

Update the adf_gen4_set_ssm_wdtimer() function to utilize this newly
introduced macro.
