tty: ar933x_uart: allow to build the driver as a module

Browse Source 
Change the SERIAL_AR933X Kconfig option from
'bool' to 'tristate' in order to allow to build
the driver as a module. Also extend the help text
of the option to reflect that.

To compile this driver as a module, choose M here: the
module will be called ar933x_uart.
