arm: rockchip: Add common cru.h Few of the rockchip family SoC atleast rk3288, rk3399 are sharing some cru register bits so adding common code between these SoC families would require to include both cru include files that indeed resulting function declarations error. So, create a common cru include as cru.h then include the rk3399 arch cru include file and move the common cru register bit definitions into it. The rest of rockchip cru files will add it in future.

rockchip: Add common reset cause Add cpu reset cause in common cpu-info file. This would help to print the reset cause for various resets. Right now it support rk3288, rk3399. rest of rockchip platforms doesn't have reset cause support ye but this code is more feasible to extend the same.

rockchip: Separate the reset cause from display cpuinfo reset cause is a generic functionality based on the soc cru registers in rockchip. This can be used for printing the cause of reset in cpuinfo or some other place where reset cause is needed.  Other than cpuinfo, reset cause can also be using during bootcount for checking the specific reset cause and glow the led based on the reset cause. So, let's separate the reset cause code from cpuinfo, and add a check to build it for rk3399, rk3288 since these two soc are supporting reset cause as of now.
