OpenWRT's dts files treat RT3050/RT3052/RT3350 within the same SoC dtsi
file, so we need to distinguish between the three dynamically, mainly
because the bit we use to determine the clock speed on RT3050/RT3052
can actually be floating on RT3350 and RT3350 is always at 320MHz.

- machine dependent low level init code
- SoC clocks detection and some utility functions
- Common interface to read/write/modify SoC system control registers, used
by some of the other drivers and utility functions
- simple FDT resets support, based on the fdt_clock implementation already
in the tree. For the moment resets and clocks are managed using these
implementations. I am planning to port those to the new extres framework
in the future, but currently I simply don't have time to do this part too.
