for the Marvell Armada 8K SoCs.

Gregory

Changelog:
v4 -> v5:

 - Rebased onto v5.0-rc1

 - Rewrite the clk_get part in armada_8k_get_sharing_cpus()

 - Reverse the call function order in armada_8k_cpufreq_exit()

v3 -> v4:

 - Remove most of the global variable and use the private data of the
   platfrom device to store the freq_tables struct.

 - Remove the clk pointer of the freq_table struct which is no more
   needed with the new way to register the opp

 - Check the get_cpu_device() return.

 - Balance the clk_get() calls.

 - No more use the devm_ function.

 - Base the registration of the opp on the cpu mask updated after each
   iteration to find the shared cpus.

 - Base the free on the NULL or 0 value of the freq_table struct
   members, it allows to remove the global index.

v2 -> v3

 - Make the driver really modular (modprobe;modprobe -r;modprobe; is working)

 - Don't use anymore 100MHz as minimal frequency, but only max frequency/4

 - Fix remaining warning reported by checkpatch

 - Rework the registering of the opp

v1 -> v2:

 - Fix typos in MAINTAINERS (reported by Baruch Siach) and in
   armada-8k-cpufreq.c (reported by Thomas Petazzoni)

 - Fix indentation in Kconfig.arm  (reported by Thomas Petazzoni)

 - Use const for opps_div  (reported by Thomas Petazzoni)

 - Fix memory leak of opps_array  (reported by Thomas Petazzoni)
