arm: v7/v8: Enable SError/Asynchronous external abort for TPL/SPL/U-Boot
Add this patch to support report SError/Asynchronous external abort
immediately in current exception level.
=== issue scene ===
When access a illegal address, It results in:
- read: Synchronous data-abort
- write: SError(64-bit)/Asynchronous external abort(32-bit)
=== 64-bit ===
EL3 SError ASynchronous exception in TPL/SPL was already
enabled in start.S and crt0_64.S which sets SCR_EL3.EA=1
and DAIF.A=0. We can test result of TPL/SPL by access address
0xfe108000 in rk3568.
Let's enable SError in U-Boot proper.
=== 32-bit ===
Let's set CPSR.A=0 to enable Asynchronous external abort, we can
test result by access address 0xfe808000 in rv1126.
Note: TPL/SPL vectors only provides "b ." for all exception entry.

armv8: add simple sdelay implementation
The sunxi DRAM setup code needs an sdelay() implementation, which
wasn't defined for armv8 so far.
Shamelessly copy the armv7 version and adjust it to work in
