serial: 8250_dw: Call dw8250_quirks() conditionally
Not all the cases provide the driver data, that is represented by
an object instance of struct dw8250_platform_data. Id est the change
missed the case when the driver is instantiated via board files as
pure platform driver. Fix this by calling dw8250_quirks() conditionally.
This will require splitting dw8250_setup_dma_filter() out of dw8250_quirks().
Also make sure IRQ handler won't crash, it also requires driver data
to be present.
Fixes: bfd3d4a40f39 ("serial: 8250_dw: Drop unneeded NULL checks in dw8250_quirks()")
