At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

If there is a '.' in a compatible string, then dtoc will produce a struct
with a name containing a '.'. This won't work, so replace it with '_'.
Also add a suitable test to the sandbox device tree to catch this.

The mpuclk register in the Altera group of the clock manager
divides the mpu_clk that is generated from the C0 output of the main
pll.
Without this patch, the default value of the register is 1, so the mpuclk
will always get divided by 2 if the correct value is not set. For example,
on the Arria5 socdk board, the MPU clock is only 525 MHz, and it should be
1.05 GHz.

This option is useful not only for development, but for the platforms
where U-Boot is run from custom ROM bootloader. For example, Intel
Edison is that board.
Make this option visible that platforms can select it if needed.

Add the correct pre-relocation tag so that the required device tree nodes
are present in the SPL device tree.
On x86 it doesn't make a lot of sense to have a separate SPL device tree.
Since everything is in the same ROM we might as well just use the main
device tree in both SPL and U-Boot proper. But we haven't implemented that,
so this is a good first step.
