From: Arnd Bergmann <arnd@xxxxxxxx> [ Upstream commit b5f73d47f34b238221ac771b5fe4907df621d7cb ] I got a build failure with CONFIG_ARCH_SPRD=m when the main portion of the clock driver failed to get linked into the kernel: ERROR: modpost: "sprd_pll_sc_gate_ops" [drivers/clk/sprd/sc9863a-clk.ko] undefined!

This is a combination of two trivial bugs: - A platform should not be 'tristate', it should be a 'bool' symbol like the other platforms, if only for consistency, and to avoid surprises like this one. - The clk Makefile does not traverse into the sprd subdirectory if the platform is disabled but the drivers are enabled for compile-testing. Fixing either of the two would be sufficient to address the link failure, but for correctness, both need to be changed.
