This patch adds support to reboot the whole board after a hardware
watchdog reset, to avoid the usual TPM issues. Work 100% equivalent to
Veyron.
From my tests it looks like both SRAM and PMUSRAM get preserved across
warm reboots. I'm putting the WATCHDOG_TOMBSTONE into PMUSRAM since that
makes it easier to deal with in coreboot (PMUSRAM is currently not
mapped as cached, so we don't need to worry about flushing the results
back before reboot).

Before, we calculate the pwm duties for cpu cores and centerlogic by
hand, adding pwm_regulator.c to handle this. The default pwm design
min/max voltage may be different between revs.
With the pwm regulator, this patch changes the little cpu frequency from
600M to 1512M, and raises CPU voltage to 1.2V correspondingly.
This also means we decide to drop the ES1 because it may fail to
bootup with 1.5G ~ 1.2v.

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.
