[PATCH 1/2] misc: vexpress_config: Use member .priv_auto to set the private data

[Qi Feng]

From: Wei Chen <wei.chen at arm.com>

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.
