serial: pic32: make SERIAL_PIC32_CONSOLE depend on SERIAL_PIC32=y

pic32_uart contains this:
  #ifdef CONFIG_SERIAL_PIC32_CONSOLE
  ...
  console_initcall(pic32_console_init);
  ...
  core_initcall(pic32_late_console_init);
  ...
  #endif
  ...
  arch_initcall(pic32_uart_init);

When the driver is built as module, all three above become
module_init(). So if SERIAL_PIC32_CONSOLE is set while SERIAL_PIC32=m,
it results in the following build error:
  In file included from include/linux/device/driver.h:21,
                   from include/linux/device.h:32,
                   from include/linux/platform_device.h:13,
                   from drivers/tty/serial/pic32_uart.c:12:
  include/linux/module.h:131:49: error: redefinition of '__inittest'

So make sure SERIAL_PIC32_CONSOLE can be set only when SERIAL_PIC32=y --
similar as for other drivers.
