perf/amlogic: Fix build error for x86_64 allmodconfig
The driver misses including <linux/io.h>, which causes a compilation
error with x86_64 'allmodconfig':
drivers/perf/amlogic/meson_g12_ddr_pmu.c: In function 'dmc_g12_get_freq_quick':
drivers/perf/amlogic/meson_g12_ddr_pmu.c:135:15: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration]
135 | val = readl(info->pll_reg);
| ^~~~~
drivers/perf/amlogic/meson_g12_ddr_pmu.c: In function 'dmc_g12_counter_enable':
drivers/perf/amlogic/meson_g12_ddr_pmu.c:204:9: error: implicit declaration of function 'writel' [-Werror=implicit-function-declaration]
204 | writel(clock_count, info->ddr_reg[0] + DMC_MON_G12_TIMER);
| ^~~~~~
Add the missing header to fix the build.
