Subject: [PATCH] arc: plat-hsdk: fix kconfig dependency warning when !RESET_CONTROLLER

When ARC_SOC_HSDK is enabled and RESET_CONTROLLER is disabled, it results
in the following Kbuild warning:

WARNING: unmet direct dependencies detected for RESET_HSDK
  Depends on [n]: RESET_CONTROLLER [=n] && HAS_IOMEM [=y] && (ARC_SOC_HSDK [=y] || COMPILE_TEST [=n])
  Selected by [y]:
  - ARC_SOC_HSDK [=y] && ISA_ARCV2 [=y]

The reason is that ARC_SOC_HSDK selects RESET_HSDK without depending on or
selecting RESET_CONTROLLER while RESET_HSDK is subordinate to
RESET_CONTROLLER.

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

Fixes: a528629dfd3b ("ARC: [plat-hsdk] select CONFIG_RESET_HSDK from Kconfig")
