Add back flushing/disabling caches for armv7 efi which was removed in
2019.04 and later and is required to load kernels on i.MX 6.
The UEFI specification states that non-architectural caches
(not controlled by cp15 operations) should be disabled during boot time
services. On i.MX 6 there is a PL310 L2 cache which U-Boot leaves on,
which breaks loading kernels even after we disable all the cp15
controlled caches in bootarm.efi.
