serial/imx: get rid of the uses of cpu_is_mx1()
The patch removes all the uses of cpu_is_mx1(). Instead, it uses the .id_table of platform_driver to distinguish the uart device type, IMX1_UART and IMX21_UART. The IMX21_UART type runs on all i.mx except i.mx1. A couple of !cpu_is_mx1 logic gets turned into is_imx21_uart, as the codes wrapped there are really IMX21 type uart specific. It also removes macro MX1_UCR3_REF25 and MX1_UCR3_REF30 which are not used anywhere.
