sunxi: Fill memory before comparing it when doing dram init on sun6i
The sun8i boot0 code fills the DRAM with a "random" pattern before comparing
it at different offsets to do columns, etc. detection. The sun6i boot0 code
does not do it, instead relying on the memory contents being random enough
to begin with for the memcmp to properly detect the wrap-around address, iow
it is working purely by chance. Since our sun6i dram code was modelled after
the boot0 code it contained the same issue.
This commit fixes this by filling the memory with a unique, distinct pattern.
The new mctl_mem_fill function this introduces is added as an inline helper
in dram.h, so that it can be shared with the sun8i dram code.
While at it move mctl_mem_matches to dram.h for re-use in sun8i too.

sun6i: clock_set_pll5: Calculate k and m rather then hardcoding them
Our old hardcoded k and m values are based on PLL5 being configured in steps
of 48 MHz, which is correct for sun6i where the DRAM PLL runs at twice the
DRAM CLK, which is usually configured in 24 MHz step. But on the A23 (sun8i)
the PLL5 runs at half the DRAM CLK, so we require 12 MHz steps.
This commit adjusts clock_set_pll5 to automatically select the best k and m
depending on the requested clk rate.

Add a specific relocate_vectors macro that skips the vector relocation, as the
i.MX25 SoC does not provide RAM at the high vectors address (0xFFFF0000), and
(0x00000000) maps to ROM.
This allows mx25 to boot again.
