This reverts commit 45f41c134b.
This weird workaround was the best I came up with at that time
to boot U-Boot from TF-A.
I noticed U-Boot successfully boots on LD20 (i.e. CA72 CPU) by using
the latest TF-A.
Specifically, since the following TF-A commit, U-Boot runs at EL2
instead of EL1, and this issue went away as a side-effect.

|
| All the SoCs in 64-bit UniPhier SoC family support EL2.
|
| Just hard-code MODE_EL2 instead of using el_implemented() helper.

However, if I reverted that, this problem would come back, presumably
because some EL1 code in U-Boot triggers this issue.
Now that commit f8ddd8cbb5 ("arm64: issue ISB after updating system
registers") fixed this issue properly, this weird workaround is no
longer needed irrespective of the exception level at which U-Boot runs.

ARM Architecture reference manual clearly states that PE pipeline

paragraph "B2.3.5 Memory Barriers" at page B2-92 of "Arm Architecture
Reference Manual ARMv8 for ARMv8-A Architecture Profile" (ARM DDI
