Add support for the RK3588 eMMC controller. This is mostly the same, with
some HS400 bits that we don't support yet. While there, fix some constants
that weren't applied to the correct registers.

dwmshc on rockchips don't support dma crossy 128M boundaries.

let controllers pass the dma boundaries to sdmmc as part of the
attach args so it can be used for the bus_dmamap_create. add the
boundary to sdhci so dwmshc can set it to be bassed to sdmmc.

tested on a radxa e25 booting and rooting off the onboard emmc.
before this diff some programs would fault with weird instructions.

get rid of some dead code.

flag the device as non-removable if the dt says it's non-removable

this may help if we end up doing suspend/resume on rk356x/rk3588.

support Designware Mobile Storage Host Controllers

this is used on rk356x and rk3588 SoCs as the emmc controller.

this is actually an sdhc(4) controller, but it has a lot of extra
registers and code for dealing with clock rates. i could have added
this to sdhc_fdt.c, but the amount of this extra code and the lack
of overlap with other chips meant id be splitting the code up based
on the chip id, which is something the autoconf/device framework
already does for us.
