staging: dgnc: dgnc_neo.c: Replace non-standard spinlock's macros

This patch replaces non-standard spinlock's macros.
It is done using coccinelle and the following semantic patch:

@@
expression x;
@@

- DGNC_SPINLOCK_INIT(x)
+ spin_lock_init(&x)

@@
expression x, y;
@@

- DGNC_LOCK(x, y)
+ spin_lock_irqsave(&x, y)

@@
expression x, y;
@@

- DGNC_UNLOCK(x, y)
+ spin_unlock_irqrestore(&x, y)

@used_by_lock exists@
typedef ulong;
symbol lock_flags;
position p1, p2;
@@

(
 ulong lock_flags@p1;

 unsigned long lock_flags@p2;
)
...
(
 spin_lock_irqsave(..., lock_flags)

 spin_unlock_irqrestore(..., lock_flags)
)

@@
position used_by_lock.p1, used_by_lock.p2;

(
- ulong lock_flags@p1;
+ unsigned long flags;
|
- unsigned long lock_flags@p2;
+ unsigned long flags;
)
<...
- lock_flags
+ flags
...>

Additionally replace 'lock_flags2' with 'flags2'.
This was done by hand since it had only 3 occurences and all in this file.
