sysutil/u-boot-rpi*: zap CONFIG_ENV_FAT_DEVICE_AND_PART
This is no longer needed with modern U-Boot and it's inaccurate for the
modern RPi. Leave the config var around for now as a hint in case
someone cares, but empty it out to avoid breaking things.

sysutils/u-boot-*: Add patch to fix MMC ordering
For FreeBSD we use a dtb overlay that switches between the sdhost and
the sdhci controller for sd card.
Recent changes in u-boot device model changed device numbering and the
sd card controller became "mmc2" for our setup which isn't accounted for
in the possible boot devices.
Patch isn't accepted yet upstream but bring this patch in for our ports anyway.
sysutils/u-boot: Update to 2020.04
While here use python3 for it as it now works.
Two slave ports have been marked broken :
u-boot-pandaboard and u-boot-duovero
Both of those boards have ~0 users in FreeBSD so if you are one of
those raise your hand.
sysutils/u-boot-rpi{3,4}: Add patch to fix PSCI stub reservation
For the traditional spin table setup, only the lowest page needs
to be reserved. However, our PSCI stubs are slightly bigger and occupy
a little over one page. These patches, already sent upstream, allow a
variable number of initial pages to be reserved for the SMP stubs. We
then set the values for these in our fragment to '2' to reserve the first
and second page.
