dmaengine: ti: k3-udma: fix -Wenum-conversion warning
gcc warns about a mismatch argument type when passing
'false' into a function that expects an enum:
drivers/dma/ti/k3-udma-private.c: In function 'xudma_tchan_get':
drivers/dma/ti/k3-udma-private.c:86:34: warning: implicit conversion from 'enum <anonymous>' to 'enum udma_tp_level' [-Wenum-conversion]
86 | return __udma_reserve_##res(ud, false, id); \
| ^~~~~
drivers/dma/ti/k3-udma-private.c:95:1: note: in expansion of macro 'XUDMA_GET_PUT_RESOURCE'
95 | XUDMA_GET_PUT_RESOURCE(tchan);
| ^~~~~~~~~~~~~~~~~~~~~~
In this case, false has the same numerical value as
UDMA_TP_NORMAL, so passing that is most likely the correct
way to avoid the warning without changing the behavior.
