Let's configure the module, but keep the legacy "ti,hwmods" peroperty to avoid new boot time warnings. The legacy property will be removed in later patches together with the legacy platform data. Note that the old sysc register offset is wrong, the real offset is at 0x1100 as listed in TRM for SATA_SYSCONFIG register. Looks like we've been happily using sata on the bootloader configured sysconfig register and nobody noticed. Also the old register range for SATAMAC_wrapper registers is wrong at 7 while it should be 8. But that too seems harmless. There is also an L3 parent interconnect range that we don't seem to be using. That can be added as needed later on.
