This error handling code can be reached before ts_dev->input is
initialized, so it is safer to always use the original name,
input_dev.

Add a number of plafrom dependent parameters to atmel_tsadcc.  The
touchscreeen driver can now take into account the slight differences
that exist between IPs included in diferent products.  This will also
allow to adapt its behaivior to the caracteristics of the resistive
panel used.

Use the function resource_size, which reduces the chance of
introducing off-by-one errors in calculating the resource size.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
struct resource *res;
@@

- (res->end - res->start) + 1
+ resource_size(res)
// </smpl>
