Revert "ARM: beaglebone: init MPU speed to 800Mhz"
Commit 130c7d6715e9 ("ARM: beaglebone: init MPU speed to 800Mhz") causes warm reboot from within Linux v5.14.0 to no longer succeed. barebox MLO is entered, but hangs. Reset from within barebox is unaffected. This can be reproduced using DistroKit 949c5ef2b9a6 ("v7a: barebox: version bump v2021.08.0 → v2021.11.0") on a Beaglebone Black. Until that's figured out, revert the commit; functional reboot is more important than the quicker boot up. This reverts commit 130c7d6715e932a1e0b3e026fea97f700ab33ea9.
