The eMMC performance on RK3399 was reduced sigificant by the commit 2cc6cde647e2 ("mmc: rockchip_sdhci: Limit number of blocks read in a single command").
That workaround should only have been applied to RK3568 and RK3588. This series fixes that and also help boost eMMC performance on two RK3399 boards even more by enabling use of SDMA.
Is there a reason to do this on just two devices?
DMA use can and should probably be enabled on other RK3399 devices, these two where the only ones I could runtime test on.

There is also an extra commit to help build a u-boot-rockchip-spi.bin image that can be used for SPI flash boot on RockPro64.
Changes in v2:
- Rebase on top of defconfig and spi v2 series
- Collect r-b and t-b tags
