[ Upstream commit 0d307935fefa6389eb726c6362351c162c949101 ]
The MIPS loongson cpufreq drivers don't build unless configured for the correct machine type, due to dependency on machine specific architecture headers and symbols in machine specific platform code.
More specifically loongson1-cpufreq.c uses RST_CPU_EN and RST_CPU, neither of which is defined in asm/mach-loongson32/regs-clk.h unless CONFIG_LOONGSON1_LS1B=y, and loongson2_cpufreq.c references loongson2_clockmod_table[], which is only defined in arch/mips/loongson64/lemote-2f/clock.c, i.e. when CONFIG_LEMOTE_MACH2F=y.
Add these dependencies to Kconfig to avoid randconfig / allyesconfig build failures (e.g. when based on BMIPS which also has a cpufreq driver).
