serial: litex: remove irrational dependency

Browse source 
Depending on `!SERIAL_SUPPORT_INTERRUPT` to enable the driver does not
make any sense, as this is a symbol selected by drivers to signify that
they support interrupts. Simply not selecting this symbol is enough to
convey the desired intention.

This fixes Kconfig problems when the driver is compiled together with
a dummy serial driver which does select `SERIAL_SUPPORT_INTERRUPT`.
