[PATCH 1/9] staging/atomisp: include linux/io.h where needed

[Arnd Bergmann]

The plat_clock implementation fails ot build in some configurations:

platform/clock/vlv2_plat_clock.c: In function 'vlv2_plat_set_clock_freq':
platform/clock/vlv2_plat_clock.c:88:2: error: implicit declaration of function 'writel';did you mean 'wrmsrl'? [-Werror=implicit-function-declaration]
platform/clock/vlv2_plat_clock.c:88:12: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration]
platform/clock/vlv2_plat_clock.c: In function 'vlv2_plat_clk_probe':
platform/clock/vlv2_plat_clock.c:193:13: error: implicit declaration of function 'ioremap_nocache' [-Werror=implicit-function-declaration]
platform/clock/vlv2_plat_clock.c:193:11: error: assignment makes pointer from integer without a cast [-Werror=int-conversion]
platform/clock/vlv2_plat_clock.c: In function 'vlv2_plat_clk_remove':
platform/clock/vlv2_plat_clock.c:209:2: error: implicit declaration of function 'iounmap' [-Werror=implicit-function-declaration]

This includes the required header file.
