The current code that rounds up the NVRAM parameter bit size to the next
byte size for the devlink parameter is not always correct. The MSIX
devlink parameters are 4 bytes and we don't get the correct size
using this method.
Fix it by adding a new dl_num_bytes member to the bnxt_dl_nvm_param
structure which statically provides bytesize information according
to the devlink parameter type definition.
Fixes: 782a624d00 ("bnxt_en: Add bnxt_en initial port params table and register it")
