freescale: Drop unnecessary cpld_data_t non-typedef

In some board cpld.h files the definition of the cpld_data struct
not-quite makes a typedef for cpld_data_t.  This problem is caught with
gcc-11 as a multiple definition error.  As there are no users of this
non-typedef, fix this by not declaring it one to begin with.
