[PATCH v2 6/7] remoteproc: stm32: Avoid directly taking address of auto_boot

The rproc->auto_boot field is going to be defined as a bit-field, which
makes it illegal to take its address in C.

To avoid build issue, a temporary boolean variable is introduced in
stm32_rproc_probe() to hold the parsed value from the device tree.
The value is then assigned to rproc->auto_boot after parsing.
