hte: tegra194: add GPIOLIB dependency

The driver started calling into a few interfaces that are part of GPIOLIB and
don't have stub implementations otherwise:

drivers/hte/hte-tegra194.c: In function 'tegra_hte_line_xlate':
drivers/hte/hte-tegra194.c:424:48: error: implicit declaration of function 'gpio_device_get_base'; did you mean 'gpio_device_get_desc'? [-Werror=implicit-function-declaration]
  424 |                 line_id = desc->attr.line_id - gpio_device_get_base(gs->gdev);
      |                                                ^~~~~~~~~~~~~~~~~~~~
      |                                                gpio_device_get_desc

Add a Kconfig dependency to only allow building when this is defined.
