Similarly to what was done for the Armada XP, this commit: * Implements the ->cpu_die() function of SMP operations by calling armada_38x_do_cpu_suspend() to enter the deep idle state for CPUs going offline. * Implements a dummy ->cpu_kill() function, simply needed for the kernel to know we have CPU hotplug support. * The mvebu_cortex_a9_boot_secondary() function makes sure to wake up the CPU if waiting in deep idle state by sending an IPI before deasserting the CPUs from reset. This is because mvebu_cortex_a9_boot_secondary() is now used in two different situations: for the initial boot of secondary CPUs (where CPU reset deassert is used to wake up CPUs) and for CPU hotplug (where an IPI is used to take CPU out of deep idle). * At boot time, we exit from the idle state in the ->smp_secondary_init() hook. This commit has been tested using CPU hotplug through sysfs (/sys/devices/system/cpu/cpuX/online) and using kexec.

However, when Armada XP is used in a !CONFIG_SMP kernel, none of these conditions are met. With Armada 370, the situation is worse: since the processor is single core, regardless of whether CONFIG_SMP or !CONFIG_SMP is used, the cache policy will be set to write-back by the kernel and not write-allocate. Since solving this problem turns out to be quite complicated, and we don't want to let users with a mainline kernel known to have infrequent but existing data corruptions, this commit proposes to simply disable hardware I/O coherency in situations where it is known not to work. And basically, the is_smp() function of the kernel tells us whether it is OK to enable hardware I/O coherency or not, so this commit slightly refactors the coherency_type() function to return COHERENCY_FABRIC_TYPE_NONE when is_smp() is false, or the appropriate type of the coherency fabric in the other case. Thanks to this, the I/O coherency fabric will no longer be used at all in !CONFIG_SMP configurations. It will continue to be used in CONFIG_SMP configurations on Armada XP, Armada 375 and Armada 38x (which are multiple cores processors), but will no longer be used on Armada 370 (which is a single core processor). In the process, it simplifies the implementation of the coherency_type() function, and adds a missing call to of_node_put().

However, they make the assumption that the coherency fabric is always available, which is currently a correct assumption but will no longer be true with a followup commit that disables the usage of the coherency fabric when the conditions are not met to use it. Therefore, this commit modifies those functions so that they check the return value of ll_get_coherency_base(), and if the return value is 0, they simply return without configuring anything in the coherency fabric. The ll_get_coherency_base() function is also modified to properly return 0 when the function is called with the MMU disabled. In this case, it normally returns the physical address of the coherency fabric, but we now check if the virtual address is 0, and if that's case, return a physical address of 0 to indicate that the coherency fabric is not enabled.

And per design team's recommendation, we should disconnect VDDHIGH and SNVS in DSM mode on i.MX6SL.
