[PATCH 09/12] rockchip: puma-rk3399: migrate to TPL

[Quentin Schulz <foss+uboot@0leil.net>]

From: Quentin Schulz <quentin.schulz@theobroma-systems.com>

Depending on the toolchain used to compile the SPL for Puma RK3399-Q7
module, the board does not boot because the resulting binary is too big
to fit in SRAM.

Let's add a TPL so that there's no need to fiddle with or hack the
defconfig to have a working bootloader.

This follows what's been done for the majority of other RK3399-based
boards.

See the original commit for the first migrations:
bdc00080111f "rockchip: rk3399: update defconfig for TPL"

Unfortunately, the offset in SPI-NOR for U-Boot proper needs to be
modified, since the move from SPL to TPL+SPL for idbloader.img (and the
"only the first 2KB per 4KB blocks are written" "hack" for rkspi format)
increased the size above 256KB. Let's move it to 512KB to, hopefully, be
safe.
