Yang Yingliang d9252b82ee tty/serial: digicolor: fix possible null-ptr-deref in digicolor_uart_probe() 
commit 447ee1516f19f534a228dda237eddb202f23e163 upstream.

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

Fixes: 5930cb3511df ("serial: driver for Conexant Digicolor USART")
