ARM: keystone: Move CPU bringup code to dedicated asm file Because of inline asm usage in platsmp.c, smc instruction creates build failure for ARM V6+V7 build where as using instruction encoding for smc breaks the thumb2 build. So move the code snippet to separate asm file and mark it with 'armv7-a$(plus_sec)' to avoid any build issues.

ARM: use const and __initconst for smp_operations These smp_operations structures are not over-written, so add "const" qualifier and replace __initdata with __initconst. Also, add "static" where it is possible.

ARM: keystone: Make PM bus ready before populating platform devices Keystone PM bus makes use of generic PM clock core backend. Since generic PM clock core uses platform bus notifiers to track events like ADD_DEVICE/DEL_DEVICE and to fill clock lists per each device, we need to initialise Keystone PM domains before the platform devices have been created. Hence, fix it by moving keystone_pm_runtime_init() before platform devices have been populated.
