media: staging: tegra-vde: Use devm_platform_ioremap_resource_byname()

There is a new devm_platform_ioremap_resource_byname() helper in the
kernel now, which helps to make code cleaner a tad by replacing few
"boilerplate" lines of code with a single line. Let's utilize that
new helper in the VDE driver.
