misc: vexpress_config: Use member .priv_auto to set the private data
In current vexpress_config_probe code, it sets the uclass private data
directly. This will cause one compilation error:
drivers/misc/vexpress_config.c:114:27: error: lvalue required as left operand of assignment
114 | dev_get_uclass_priv(dev) = priv;
| ^
In this patch we set the uclass private data through struct member
.priv_auto, and this compilation error disappears.
