[PATCH] wan: wanxl: Remove typedefs from struct names

[Himangi Saraogi]

The Linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedefs for
port_t, card_status_t and card_t. Also, the names of the structs
are changed to drop the _t, to make the name look less typedef-like.

The following Coccinelle semantic patch detects two cases and a
similar one detects the case for card_t.

@tn1@

typedef struct { ... } td;
