On the RK3399-Q7, we need to turn on the on-module USB hub before using the
USB host interfaces (only the OTG interface is directly connected to the edge
connector). This drops the deprecated 'rockchip,vbus-gpio' property and uses
a fixed regulator to turn on the USB hub.

When creating a EFI/GUID partition map for the RK3399-Q7 through
U-Boot, the partition entries should be places at a 1MB offset from
the start of the device to give us space for the environment (at 16KB
on SD/MMC devices), the SPL stage (at 32KB on SD/MMC devices) and the
image payload (at 256KB on SD/MMC devices).
This change sets this up through the u-boot,efi-partition-entries-offset
/config property in the RK3399-Q7 DTSI.

As our SPL stage can grow quite large (80KB+ are not unusual) on the
RK3399-Q7, the default setting for the environment location (in
include/configs/rockchip-common.h) can overlap our SPL.
This change finally makes use of the 'u-boot,mmc-env-offset' DTS
property to override the environment location and put it at 16KB into
the device, which is right before the SPL (located at 32KB).

To better support different RAM timings (DDR3-1333 and DDR3-1866 are
assembly options for the RK3399-Q7), this refactors the DTS support
and renames the default DTS variant from rk3399-puma to
rk3399-puma-ddr1600:
- changes the rk3399-puma DTS into a board-specific DTSI by removing
the inclusion of the DRAM timings
- adds a new rk3399-puma-ddr1600.dts, which includes the (new) common
board DTSI and the DDR3-1600 timing DTSI
- wires this up from arch/arm/dts/Makefile and configs/puma-rk3399_defconfig
