[PATCH] pinctrl: PINCTRL_ROCKCHIP should depend on ARCH_ROCKCHIP

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

The Rockchip GPIO and pin control modules are only present on Rockchip
SoCs.  Hence add a dependency on ARCH_ROCKCHIP, to prevent asking the
user about this driver when configuring a kernel without Rockchip
platform support.

Note that before, the PINCTRL_ROCKCHIP symbol was not visible, and
automatically selected when needed.  By making it tristate and
user-selectable, it became visible for everyone.

Fixes: be786ac5a6c4bf4e ("pinctrl: rockchip: make driver be tristate module")
