[ Upstream commit bb162bb2b4394108c8f055d1b115735331205e28 ]

When PHY_SUN6I_MIPI_DPHY is selected, and RESET_CONTROLLER is not selected, Kbuild gives the following warning:

WARNING: unmet direct dependencies detected for PHY_SUN6I_MIPI_DPHY Depends on [n]: (ARCH_SUNXI [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] && COMMON_CLK [=y] && RESET_CONTROLLER [=n] Selected by [y]: - DRM_SUN6I_DSI [=y] && HAS_IOMEM [=y] && DRM_SUN4I [=y]

This is because DRM_SUN6I_DSI selects PHY_SUN6I_MIPI_DPHY without selecting or depending on RESET_CONTROLLER, despite PHY_SUN6I_MIPI_DPHY depending on RESET_CONTROLLER.

These unmet dependency bugs were detected by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution.

v2: Fixed indentation to match the rest of the file.
