Make get_tclk and get_cpu_freq generic for Marvell armv7 SoCs

Browse Source 
In GENERIC kernel choosing proper get_tclk and get_cpu_freq implementation must
be done in runtime. Kernel for both SoC need to have implementation of each
other functions, so common file list mv/files.arm7 is added.
Marvell armv5 SoC have their own non-generic implementation of those function.
