The amba core throws a warning if -1 is used as an
irq value since upstream commit:
2eac58d5026e4ec8b17ff8b62877fea9e1d2f1b3
ARM: amba: make use of -1 IRQs warn
Make the core warn about the use of -1 (NO_IRQ)
Cange the value of the unused IRQs to zero for the
UART devices to get rid of the warning.
Based on #12729.
