Davinci: Table driven pinmux configuration
Davinci: Table driven pinmux configuration
Add code to allow pinmux_config tables to be grouped and configured
as a single resource. This removes multiple calls to the pinmux
configuration code from board_init and allows pinmuxes to be
individually configured and added by data manipulation only.
All related #ifdefs can the be removed from board_init code and
since the compiler optimises away statics, #ifdefs can be reduced in
the data definitions as well.
