Use helper functions chip_{read,write}[bwl] to access flash chips

Browse Source 
The semantic patch I used in r418 to make the original conversion to
accessor functions was missing one isomorphism:
a[b] <=> *(a+b)

The semantic patcher Coccinelle was used to create this patch. Semantic
patch follows:
@@
typedef uint8_t;
expression a;
volatile uint8_t *b;
@@
- b[a]
+ *(b + a)
@@
expression a;
volatile uint8_t *b;
@@
- *(b) = (a);
+ chip_writeb(a, b);
@@
volatile uint8_t *b;
@@
- *(b)
+ chip_readb(b)
@@
type T;
T b;
@@
(
 chip_readb
|
 chip_writeb
)
 (...,
- (T)
- (b)
+ b
 )

Corresponding to flashrom svn r498.
