-Instead of defining an enumeration with the FW specific values for the
-different clock rates, use the actual frequency instead. Also add a
-boolean to specify whether the clock is XTAL or not.
-
-Change all board files to reflect this.
-
-Additionally, this reverts commit 26f45c (ARM: OMAP2+: Legacy support
-for wl12xx when booted with devicetree), since this is not be needed
-anymore, now that DT support for WiLink is implemented.
