[dpdk-dev] [PATCH v2 29/36] net/ice/base: move functions from common to NVM module

[Qi Zhang <qi.z.zhang@intel.com>]

The ice_get_pfa_module_tlv and ice_read_pba_string functions primarily
deal with reading from the Shadow RAM portion of the NVM contents. As
these functions are NVM focused, move them into the ice_nvm.c file.
