Staging: wilc1000: Remove and rename struct typedefs from .c files

Using typedef for a structure type is not suggested in Linux kernel coding
style guidelines. So remove typedefs from structures wilc_sdio_t,
wilc_spi_t and wilc_mac_cfg_t.
Also remove '_t' suffix from the struct names by hand.

The following semantic patch detects cases:

@tn1@
type td;
@@

typedef struct { ... } td;

@script:python tf@
td << tn1.td;
tdres;
@@
coccinelle.tdres = td;

@@ type tn1.td;
identifier tf.tdres;
@@
-typedef
 struct
+ tdres
  { ... }
-td
  ;
@@ type tn1.td;
identifier tf.tdres;
@@
-td
+ struct tdres
