Rename RX and TX packet buffer size macros in preparation for an upcoming patch that will refactor buffer size handling using FIELD_PREP and GENMASK. Changes: - Rename I225_RXPBSIZE_DEFAULT to IGC_RXPBSIZE_EXP_BMC_DEFAULT. The EXP_BMC suffix explicitly indicates Express and BMC buffer default values, improving readability and reusability for the upcoming changes, while also better reflecting the current buffer allocations. - Rename I225_TXPBSIZE_DEFAULT to IGC_TXPBSIZE_DEFAULT. These registers apply to both i225 and i226, so using the IGC prefix aligns with existing macro naming conventions.
