dmaengine: pl330: rename _start to prevent build error

"_start" is used in several arches and proably should be reserved
for ARCH usage. Using it in a driver for a private symbol can cause
a build error when it conflicts with ARCH usage of the same symbol.

Therefore rename pl330's "_start" to "pl330_start_thread" so that there
is no conflict and no build error.

drivers/dma/pl330.c:1053:13: error: '_start' redeclared as different kind of symbol
 1053 | static bool _start(struct pl330_thread *thrd)
      |             ^~~~~~

   11 | extern char _start[];
      |             ^~~~~~
