rockchip: adding the missing "/" in entries of boot_devices
Without the prefix, "same-as-spl" in `u-boot,spl-boot-order` will not work
as expected. When board_boot_order() `spl-boot-order.c` meets
"same-as-spl", it gets the conf by looking the boot_devices table by boot
source, and parse the node by the conf with:
node = fdt_path_offset(blob, conf);
which will failed without the "/" indicating the path.
Currently only entries of boot_devices in rk3399 have the "/" prefix.
Therefore add the missing ones in other boards.

Makefile: fix dependency for imx targets

make -f /home/hs/abb/mainlining/u-boot/scripts/Makefile.build obj=arch/arm/mach-imx u-boot-dtb.imx

make[1]: Leaving directory '/work/hs/compile/u-boot/aristainetos2_defconfig'

compile failed
In above case of CONFIG_MULTI_DTB_FIT is defined, the
u-boot-dtb.imx is dependent on the u-boot-fit-dtb.bin
which may is not build yet ...
I could reproduce this error on a travis build also if
I build an out-of-tree build on a local machine with a
build directory on a "slow" slow storage device. If
building the same source target with a build dir on a
fast storage device, the build works.
I found no solution to tell the arch/arm/mach-imx/Makefile
to find the targets in main Makefile, if there is a way
this would be the better fix.
I solved it by adding a IMX_DEPS var, which holds a list
of main u-boot targets, which must be finished, before
calling imx targets and fixed the build for imx
targets which enabled CONFIG_MULTI_DTB_FIT.
I think it is just luck, that imx targets with
CONFIG_OF_SEPARATE enabled build, because the
u-boot-dtb.imx target depends on u-boot-dtb.bin
which gets build early enough before starting with
u-boot-dtb.imx. May this targets should be fixed too.

arm: mxs: Increase VDDD voltage to match specification
According to IMX28CEC rev. 4, 10/2018, Table 15. Recommended Operating
Conditions, page 16, the VDDD should be set to 1.55V when the CPU is
operating at 454MHz. This is the case in U-Boot, hence increase the
VDDD voltage. This fixes instability when performing TFTP transfers.
Increase the brownout threshold to 1.4V. The documentation recommends
1.45V setting for the brownout, however, this triggers failure during
power block init, so keep the brownout slightly lower.
