ibm_newemac: Introduce mal_has_feature
There are some PowerPC SoCs that do odd things with the MAL handling. In order to accommodate them, we need to introduce a feature mechanism that is similar to the existing emac_has_feature function. This adds a feature variable to the mal_instance structure, and adds a mal_has_feature function. Two features are defined and are guarded by Kconfig options that are selected by the affected platforms. MAL_FTR_CLEAR_ICINSTAT is used for platforms that need to clear the interrupt bits in the ICINTSTAT SDR for txeob/rxeob. This is common on MAL implementations that have interrupt coalescing. MAL_FTR_COMMON_ERR_INT is used for platforms that have SERR, TXDE, and RXDE OR'd into a single interrupt bit.
