[PATCH net-next v2 1/1] i40e: Add missing wordpart.h header

When cleaning up another header I have met this build error:

drivers/net/ethernet/intel/i40e/i40e_hmc.h:105:22: error: implicit declaration of function 'upper_32_bits' [-Wimplicit-function-declaration]
  105 |         val1 = (u32)(upper_32_bits(pa));                                \

This is due to missing header, add it to fix the possible issue.
