The following patch is a first step to convert the 'struct pad_desc' to a bitmapped cookie to facilitate adding platform specific pullup or drive strength definitions to existing pad definitions without need to rewrite the complete pad def. The patch wraps 'struct pad_desc' in an opaque data type and introduces macros to access the individual members. This patch does not constitute any functional change!
