mtd: txx9ndfmc: use devm_request_and_ioremap

Reimplement a call to devm_request_mem_region followed by a call to ioremap
or ioremap_nocache by a call to devm_request_and_ioremap.

The semantic patch that makes this transformation is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@nm@
expression myname;
identifier i;
@@

struct platform_driver i = { .driver = { .name = myname } };

@@
expression dev,res,size;
expression nm.myname;

-                              \(res->name\|dev_name(dev)\|myname\))) {
-   ...

-}

+devm_request_and_ioremap(dev,res)
)
... when any
    when != res->start
