brcmfmac: Use put_unaligned_le32

This patch introduces the use of function put_unaligned_le32.

This is done using Coccinelle and semantic patch used is as follows:

@a@
typedef u32, __le32, uint32_t;
{u32,__le32,uint32_t} e32;
identifier tmp;
expression ptr;
expression y,e;
type T;
type T;
@@

- tmp = cpu_to_le32(y);

<+... when != tmp
(
- memcpy(ptr, (T)&tmp, \(4\|sizeof(u32)\|sizeof(__le32)\|sizeof(uint32_t)\|sizeof(e32)\));
+ put_unaligned_le32(y,ptr);
|
- memcpy(ptr, (T)&tmp, ...);
+ put_unaligned_le32(y,ptr);
)
...+>
? tmp = e

@@ type T; identifier a.tmp; @@

- T tmp;
...when != tmp
