Add initial configuration parameters for Rasperry Pi 3's sdhost
controller, and then configure and use those parameters.
This change allows warm reboots of UEFI on Raspberry Pi 3B+ where
existing code often fails with "unknown error". See discussion at:
https://github.com/pftf/RPi3/issues/24
The basic idea is that some initial configuration parameters
(clock rate, bus width) aren't configured into the hardware before
commands start being sent. I suspect that the particular setting
that matters is the "slow card" bit, but the initial clock setting
also seemed wrong to me.
