rockchip: Fix rkimage format for SPL boot over USB
The 'rkimage' format used for booting rockchip boards over USB seems to
have been broken since commit 7bf274b9caab ("rockchip: mkimage: use

RK_SPL_HDR_START(=2048) to the location the 'RKxx' header is written
at. However the bootrom expects this header to be the first four bytes of
the image, not at offset 2048. This appears to have been a copy paste
error since the 'rksd' and 'rkspi' image types do require this offset.
Furthermore commit 111bcc4fb6cb ("rockchip: mkimage: pad the header to
8-bytes (using a 'nop') for RK3399"), commit 3d54eabcafec9 ("rockchip:
spl: RK3399: use boot0 hook to create space for SPL magic") and

spi: Add SPI driver for MT76xx SoCs
This patch adds the SPI driver for the MediaTek MT7688 SoC (and
derivates). Its been tested on the LinkIt Smart 7688 and the Gardena
Smart Gateway with and SPI NOR on CS0 and on the Gardena Smart
Gateway additionally with an SPI NAND on CS1.
Note that the SPI controller only supports a max transfer size of 32
bytes. This driver implementes a workaround to enable bigger xfer
sizes to speed up the transfer especially for the SPI NAND support.
