Subject: [PATCH] pinctrl: starfive: use dynamic GPIO base allocation

The JH7110 pinctrl driver currently sets a static GPIO base number from
platform data:

  sfp->gc.base = info->gc_base;

Static base assignment is deprecated and results in the following warning:

  gpio gpiochip0: Static allocation of GPIO base is deprecated,
  use dynamic allocation.

Set `sfp->gc.base = -1` to let the GPIO core dynamically allocate
the base number. This removes the warning and aligns the driver
with current GPIO guidelines.

Tested on VisionFive 2 (JH7110 SoC).
