[PATCH] i2c/i2c-mxs: use devm_request_and_ioremap

[Peter Huewe]

Replace a call to devm_request_mem_region followed by a call to
dev_ioremap_nocache with devm_request_and_ioremap which does the same.
And since res_size isn't needed anymore we can remove it as well.

Found with coccicheck and this semantic patch:
 scripts/coccinelle/api/devm_request_and_ioremap.cocci.
