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.
