Subject: sun6i: Sync PLL1 multipliers/dividers with Boot1
This change syncs up the multipliers and dividers used to initialize
PLL1 (i.e. the fast clock driving the ARM cores) with the values used
in Allwinner's Boot1 on sun6i.
More specifically, the following settings are now used:
* up to 768MHz: mul=2, div=2 (was: mul=1, div=1)
* up to 1152MHz: mul=3, div=2 (unchanged)
* above 1152MHz: mul=4, div=2 (was: mul=2, div=1)

Subject: sun6i: Fix and document PLL LDO voltage selection
The PRCM_PLL_CTRL_LDO_OUT_L and PRCM_PLL_CTRL_LDO_OUT_H macros had
their meaning reversed. This is fixed by this change-set. With this
changed, the PRCM_PLL_CTRL_LDO_OUT_L(1370) now becomes self-evident
as setting the voltage to 1.37v (which it had done all along, even
though stating a different target voltage).
After changing the PLL LDO setting, it will take a little while for
the voltage output to settle. A sdelay()-based loop waits the same
order of magnitude as Boot1.
Furthermore, a bit of documentation is added to clarify that the
required setting for the PLL LDO is 1.37v as per the A31 manual.

Subject: mkimage: check environment for dtc binary location
Currently mkimage assumes the dtc binary is in the path and fails
otherwise. This patch makes it check the DTC environment variable first
for the dtc binary and then fall back to the default path. This makes
it possible to call the u-boot build with make DTC=... and build a fit
image with the dtc binary not being the the default path.

version v1.4.3")
OpenWrt uses the dtc from the kernel also in u-boot, but when we compile
against kernel 4.9 we run into some errors because it is too old now.
Add the options only when they are supported to make it compatible with
dtc from kernel 4.9.
