Yang Yingliang f7a440c89b i2c: mux: reg: check return value after calling platform_get_resource()

[ Upstream commit 2d47b79d2bd39cc6369eccf94a06568d84c906ae ]

It will cause null-ptr-deref in resource_size(), if platform_get_resource()
returns NULL, move calling resource_size() after devm_ioremap_resource() that
will check 'res' to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.
