This patch list four frequencies for ddr controller,
200MHz, 300MHz, 666MHz and 800MHz and configure
each freq by setting the DPLL dividers.
By default, the clk_ddrc is from DPLL and equals to DPLL,
so here we only need to set the DPLL clock.

This patch initialize the PLL clocks and add function to
configure cpu freq. Right now, we set the little cpu freq to 600MHz.
In coreboot, we currently care about these four PLLs,
o. APLL for cpu clk, where A stands for AXI,
o. CPLL and GPLL are the generic PLL mainly for peripheral clk,
o. PPLL is only PMU clk.
For the peripheral clocks, there are thress clocks named as,
aclk_perihp,
aclk_perilp0,
hclk_perilp1,
where the 'h' and 'l' letters refer to High and Low speed.
As the diagram below, the aclk_perihp always be the parent of
more higher speed peripheral devices like pcie, and
hclk_perilp1 for spi, i2c, aclk_perilp0 for crypto.
These three clocks can choose parent from GPLL or CPLL freely,
in this patch, they are all sourced from GPLL.

Quoting an earlier review comment, using static structures pointers in
the include file "should allow the compiler to optimize accesses
better than defining it in a separate compilation unit (by being able
to constant fold stuff like &rk3399_pmusgrf->field into a single
address, rather than loading the symbol, loading an offset constant
and adding)".
Any decent compiler linker system nowadays would consolidate this
definition in any case.

To avoid diverging too much on an actively developed code base, keep
the changes to a separate commit that can be downstreamed more easily:
- removed unused includes
- gave kevin board a "Kevin" part number
- marked RW_LEGACY as CBFS region (to follow up upstream changes)
- moved romstage entry point to SoC code (instead of encouraging
per-board copy pasta)
